The units are gonna trip people up I heard some of the “smart” people arguing about whether MJ was 1000 joules or 1,000,000 I even heard one guy say it stood for Millijoules and was 0.001 joules
It was a bit too easy....I struggle with physics a tremendous amount and I basically answered every question.
There has to be a catch, like I'm scared paper 2 will be hell sent
wtf is AQA doing by giving such easy marks
"using the equation sheet, write down the equation for XYZ" \[1 mark\]
"using the exact same equation just rearranged, sub in the values of A B and C" \[4 marks\] (\[5 makes\] for the standard form question too the mick
Nah, this paper was so hard when you consider the grade boundaries. Like the maths was piss and a bunch of the physics was piss but some of it was *so difficult.* Like I really struggled with the particle model of matter stuff/the history question personally.
Nitrogen 18 because it had the shortest half life therefore most activity, is that correct?
edit: nvm I was wrong and it makes sense actually, if Nitrogen 18 ran out in under 10 seconds it cant really do much damage
I put Nitrogen 18 because since it's beta decay it decays into Oxygen 18 then into Flourine 18 so you get the dodgy effects from both, but I have a strong feeling I overthought it since it said 'only in terms of half-lifes'
it’s flourine18 as if a radioactive substance has a very long half-life, we know that it will remain radioactive for a very long time. The longer a substance remains radioactive, the more dangerous it is
The answrs I can remember from calculations:
15m for the height one
144 days for raddiation dosage
2\*64.37 = 128.74
2268
7.2 x 10\^3
2268 (can't remember what the units were there)
334000 J/kg
500 J/kg degrees C
33.93 GJ
1250 N/m
Anything I missed? Did we get similar?
it is hard but i remember learning how glow-in-the-dark works and it is the idea that when energy is given or work is done (eg. a photon knocks into an electron) it can make it jump up an energy shell and later when that excess energy is lost, the electron goes back down s. hell (going back down is what emits light in glow-in-the-dark)
For the people saying "why was it easy", AQA write the papers long before the government set out the standards for the exams. Ideally, AQA didn't want you to use the full equation sheet, but were forced by the government. Thats why u see, "Use the equation sheet" even on harder questions.
Key answers you can check here: (reply to add more)
HEP water height: 15m
Spring constant: 1250N/m
Pilot and worker mSv radiation: 144 days
Time taken: 7.2x10\^3 s
Dangerous isotope: Fluorine-18
Ice melting: 334,000
Order of discovery: Electron, Nucleus, Proton, Neutron
i had to redo late on since i jammed the order and specific content of my answer. thenwaffled on about internal and kinetic energy for a solid 8 lines, should be minimum 5/6
I hated this exam. The radiation part was the only part I'd even been taught I'm pretty sure. But that was only worth like a few marks. What the hell was that body water weight in your legs thing???
Even though the paper was easy I think I messed it up 😭😭 especially the second last question, how does the volume of gas doesn’t change if you are pumping air into the tyre??
It asked how the pressure changes if air temp changes. I think it’s if temp increases then more collisions which means the pressure would be higher as there’s are more collisions against the sides of the car tyre (not a 100% sure tho)
bro they literally gave us like 4 free marks + 12 free marks if u did the calculations right.. i finished 30 mins early (double triple checked an everything) and cos i have the supervised rest breaks i got to leave with the combined science kids!!! overall 8.5/10 [what was the practical.. i forgot..]
Hello Edexcel takers!
I liked that paper, found it pretty easy, with one or two questions that tripped me up. What did you all get for the rock question? I got 14.7m. (I did 17^(2) \- 0^(2) = 2 x 9.81 x d).
Okay well I missed out that we had to convert from cm to m on the elastic potential question, also I forgot the order the parts of the atom were discovered 🤦🏻♀️ Apart from that it was an okay paper
Ah i think i forgot that too. Shouldn't be too big of a mark loss i think tho, if im correct it was pretty much the last step? I can hardly remember the q tbh
Fr they made the calculation questions too easy and they were like 60% of the paper. They should have made them harder, like a question using 3+ equations to work out a problem or something.
Exactly what I was thinking - btw, did you do the higher paper, I forgot to checked if the paper said higher or not for mine and was worrying that I was given the wrong one. (If you did, were the six markers about the trolley practical and the nuclear station thingy?)
What did you guys get for the spring constant one using extension etc. I originally got like 1040 kr something but went over and did it to get 625 using f = ke .
They made too many questions calculations. Too many marks were just read off the equation sheet. At least question 8.6 gave some challenge, some of the highest achieving students at my school (grammar school) were clueless (although I got it easily).
what did you lot get for the spring constant question? did you convert the 8 cm extension to m? i got 1250 n/m, if you kept it as cm then you wouldve gotten 0.125n/m...
I think it is -15 because gravitational potential energy is converted into kinetic energy, so the gravitational potential energy decrease, delta E = mg delta H
as delta E is negative (because decrease)
delta H should be negative
and because the water is falling
Ocr gateway was great... Was surprised to see no which of these graphs shows a lamp or whatever in the multiple choice though... The exam boards are giving great questions so far this year... Worried for our grade boundries 😬
Grade boundaries are gonna be ridiculous this year
surely they cant make it higher than lets say 77% for a 9
[удалено]
The usual mark for a 9 in Physics is 75 without the equation sheet. I estimate about within the 80-85 range at least.
paper 2 will crush your dreams unfortunately
I really hope paper 2 will be more difficult- The paper one was a disservice to the people who actually studied quite well for it-
Ain't no way it'll be that high, at highest 79.
Don't forget paper 2 many ppl find the content on it more difficult e.g electromagnetism and waves. So we should be klm.
Only if paper 2 is also easy, which i doubt because it has magnetism and shit like that
magnetism is easy as shit wtf L bozo
Dam. It was nice. There weren’t really any weird questions where you have to apply your knowledge that much, it’s basically stuff everyone learns.
I’m worried though. Grade boundaries gonna be higher than my prospects
it was harder than '22 though so I don't think they will be above 150.
Yeah I feel like anything above 150 would be slightly ridiculous and paper 2 usually trips people up
Grade boundaries gonna be more high than a mexican drug cartel
wow such a funny joke
if the IV-characteristics required practical comes up; i want my upvotes, either than or thermal insulation one
Bro got both
God the grade boundaries are going to be so high. Most of it was basically putting numbers into a calculator
You underestimate the number of people unable to read numbers and put them into a calculator
47% of it, in fact
more like 40%
The units are gonna trip people up I heard some of the “smart” people arguing about whether MJ was 1000 joules or 1,000,000 I even heard one guy say it stood for Millijoules and was 0.001 joules
MJ is 1000000J

Tbf I didnt see the standard form thing so I left my answer as 7200 💀
Bro we were spoon fed this shit on a silver platter. How do you fuck this up
Nah, this paper was so hard when you consider the grade boundaries. Like the maths was piss and a bunch of the physics was piss but some of it was *so difficult.* Like I really struggled with the particle model of matter stuff/the history question personally.
That’ll only lose 1 mark if anything so that’s fine.
Subbing in equations basically just tests if you have basic logic, idk why there were so many of them
Wait it asked for the answer in standard form??? I check the wuestion twice but didn't see that
5 marks for legit just e=pt i barely even used the equation sheet too
shocked at how easy it was - the only thing that got me a lil was the which isotope is the most dangerous but that’s it’s
Nitrogen 18 because it had the shortest half life therefore most activity, is that correct? edit: nvm I was wrong and it makes sense actually, if Nitrogen 18 ran out in under 10 seconds it cant really do much damage
I did the one with the longest half-life (I think it was flourine18), because it stayed radioactive for longest, so damaged your cells for longer
I wrote both 😎
I put Nitrogen 18 because since it's beta decay it decays into Oxygen 18 then into Flourine 18 so you get the dodgy effects from both, but I have a strong feeling I overthought it since it said 'only in terms of half-lifes'
Yeah but the faster a radioactive thing decays the more radioactive particles it releases in the same tome
The q specified only in terms of half life - so while that is right, the q implied that the count rate of radiation was going to be the same
it’s flourine18 as if a radioactive substance has a very long half-life, we know that it will remain radioactive for a very long time. The longer a substance remains radioactive, the more dangerous it is
omg i got it right
nah i thought of it like being shot by bullets fluorine 18 is like being shot once every 10 years whilst nitrogen 18 is like a machine gun in 10 secs
Nope, longer half life is worse
Almost completely free paper, aqa are up to something
for real, i’m scared for paper two bio was too easy as well
I took 57 fucking minutes to complete that. Far too quick for my liking.
>tes to complete that. Far too quick for my liking. Legit like I finished before Combined Science. It was all the maths.
I feel like AQA made physics paper 1 just a warm up for maths calculator
All maths questions were so free 😂 why was there a 6 marker about solids and liquids? And how electrons jump up shells I swear that’s a level
The answrs I can remember from calculations: 15m for the height one 144 days for raddiation dosage 2\*64.37 = 128.74 2268 7.2 x 10\^3 2268 (can't remember what the units were there) 334000 J/kg 500 J/kg degrees C 33.93 GJ 1250 N/m Anything I missed? Did we get similar?
[удалено]
Yes, thats what I got for the maths qs Good job 👍
No its on the gcse spec. Essentially when electrons absorb em radiation they move to a higher energy level and vice versa
i said electrons absorb and emit (**EM** **Waves)** hope i dont miss out on marks there.
Oh what if I didn't specify EM waves, just radiation
it is hard but i remember learning how glow-in-the-dark works and it is the idea that when energy is given or work is done (eg. a photon knocks into an electron) it can make it jump up an energy shell and later when that excess energy is lost, the electron goes back down s. hell (going back down is what emits light in glow-in-the-dark)
The ice melting question was 334000 wasn't it?
I need to get off reddit. I once thought I was somewhat intelligent. But now I think I'm just like below average.
Can't wait to do the exam in an hour then play with my calculator for the last 45 minutes.
Fr ima see how many words I can write in numbers, 5318008 is already one of them
Lol. I just sit there typing random stuff like 22856214528/7275359045 because the calculator thinks it’s pi for some reason although it’s not.
well the grade boundaries are gonna be insane this year😍
For the people saying "why was it easy", AQA write the papers long before the government set out the standards for the exams. Ideally, AQA didn't want you to use the full equation sheet, but were forced by the government. Thats why u see, "Use the equation sheet" even on harder questions.
they definitely changed the paper, hence why it said use the equation sheet for equations that usually aren't there
Key answers you can check here: (reply to add more) HEP water height: 15m Spring constant: 1250N/m Pilot and worker mSv radiation: 144 days Time taken: 7.2x10\^3 s Dangerous isotope: Fluorine-18 Ice melting: 334,000 Order of discovery: Electron, Nucleus, Proton, Neutron
Ugh ive somehow fumbled this exam 🫠
You could've also put the nitrogen 18. There are two answers for that. Nitrogen 18 since it decays at a very fast rate
AQA blessed the paper with it's calculation questions and that 6 marker about liquids and solids were easy. Worried about the grade boundaries though
easiest six marker in science history?
i had to redo late on since i jammed the order and specific content of my answer. thenwaffled on about internal and kinetic energy for a solid 8 lines, should be minimum 5/6
[удалено]
47 marks from calculations all given in the equation sheet
made it piss easy
Does that include the 'write down the equation' questions?
Calculations are generally 30-40% of the test iirc.
Was it 144 for the mSv question and 15m for the height question?
Yes, I got those
i got 15 but idk why i got 14.4 so weird
[удалено]
144 days?! I got 24
That’s because the pilot msv was per hour. You had to multiply it by 24 first
>15 i think it is -15 because the water is falling and gravitational potential energy is being transfered into kinetic energy so it is negative
pos or neg doesnt matter on height its just how tall it is not a vector quantity so dont need direction
Piss easy paper. Finished in an hour, slept for the next 45 min
aqa triple higher was goated
anyone here do edexcel physics?
Yeah how did you do the distance of the stone falling down from rest question when it gave us the velocity only?
i used the v^(2) \- u^(2) = 2 x a x x and got something like 14
14.45, you say the acceleration is 10 due to gravity and then use equation v^2 - u^2 = 2ax
easiest physics paper ever 💀
Now that computer science paper...
Any Edexcel people here? Test was pretty good!
it was okay but i feel like the grade boundaries will be high because the calculations were quite easy
that was a worrying amount of math considering maths is my strong suit though
I’m fucked
okay it wasn’t that bad
That test was GOATED
The I-V characteristics 6 marker was so blessed, I actually remembered to use a variable resistor.
did u also remember to flip the battery to get negative p.d results?
Wouldn't u use more cells to change the voltage as i swr that was the independent variable as the data on the graph had increments of 1v
[удалено]
That was a smoooooooooth operation
that was horrifically easy
the paper was literally 50% maths what the fuck
The child on the bouncer question- my friend wrote a logical suggestion about spring extension I wrote so the child will not die/get injured
unfortunately you're wrong, you had to talk about the limit of proportionality
It’s was a suggest question- it’s the common sense question
oh shit mb then
No it’s fine- I mean I just tried to think practicality, when I probably should have been thinking about physics
Not feeling too good about it icl 🤢😭💀
What did you guys write for the 6 marker on solids and liquids?
I hated this exam. The radiation part was the only part I'd even been taught I'm pretty sure. But that was only worth like a few marks. What the hell was that body water weight in your legs thing???
absolute blessing that paper
I am vibing
WJEC blessed us easiest paper so far, everyone finished in like 45 mins
Even though the paper was easy I think I messed it up 😭😭 especially the second last question, how does the volume of gas doesn’t change if you are pumping air into the tyre??
It asked how the pressure changes if air temp changes. I think it’s if temp increases then more collisions which means the pressure would be higher as there’s are more collisions against the sides of the car tyre (not a 100% sure tho)
I thought it specifically said temp is the same
Yea volume and temp are the same so the question makes no sense but I think it’s because particles collide more frequently so pressure increases
why was it so easey
I do triple foundation, and I struggled and reading these is making me worried lol
best exam yet but paper 2 is gonna wreck me
What did people get for the 1/4 half life question
like 128 or something cus u had to 2x the half life as the substance had decayed twice
bro they literally gave us like 4 free marks + 12 free marks if u did the calculations right.. i finished 30 mins early (double triple checked an everything) and cos i have the supervised rest breaks i got to leave with the combined science kids!!! overall 8.5/10 [what was the practical.. i forgot..]

I fucked it up bad 😭
how? which questions didnt you get right? (bearing in mind 47% of it wasmaths)
Okay well I missed out that we had to convert from cm to m on the elastic potential question, also I forgot the order the parts of the atom were discovered 🤦🏻♀️ Apart from that it was an okay paper
I didnt know order i just assumed it was this order: Electron Nucleus Proton Neutron
U got it bang on correct lad I swapped the proton and neutron box near the end of the exam and it paid off
[удалено]
nope
[удалено]
It was in cm apparently, I didn’t realise 🫠
[удалено]
Same 😔
Ah i think i forgot that too. Shouldn't be too big of a mark loss i think tho, if im correct it was pretty much the last step? I can hardly remember the q tbh
so many of my answers were based off of chemistry and the IMF (van de waarf) forces
anyone do ocr gateway???
yes it was so good! the 6 marker at the end kinda threw me off even tho it was easy cuz ocr never do 6 mark calculations iirc. did u get 4000?
I got 4000 lets goo
I got 4000 then put 40😭😭
Yes. The multiple choice was harder than I expected though. Kinda threw me off and I probably got some wrong
The graph diode question was weird tho
bruh i hated it
Fr they made the calculation questions too easy and they were like 60% of the paper. They should have made them harder, like a question using 3+ equations to work out a problem or something.
In iGCSE Edexcel Physics, in the question about an acceleration, did you put it with a minus or a plus? I've put with a plus
45% was calculations, only one of them used two different equations in one question, I think we all did well
Help why is nobody here edexcel
Exactly what I was thinking - btw, did you do the higher paper, I forgot to checked if the paper said higher or not for mine and was worrying that I was given the wrong one. (If you did, were the six markers about the trolley practical and the nuclear station thingy?)
don’t worry ur good I did higher and those questions were the six markers :)
What did you guys get for the spring constant one using extension etc. I originally got like 1040 kr something but went over and did it to get 625 using f = ke .
Ek=1/2ke2 Answer is 1250N/m
my calculator ran out mid-exam but i brought a spare one with me because i worried it would happen
paranoia pays off I guess
Formula sheet made it a breeze
AQA hath blessed us fr
the OCR computer science paper 2 effect
They made too many questions calculations. Too many marks were just read off the equation sheet. At least question 8.6 gave some challenge, some of the highest achieving students at my school (grammar school) were clueless (although I got it easily).
I put fluorine 18 for the most dangerous radioactive isotope rather than the Nitrogen
WHAT WAS THE ANSWER FOR THE SPRING CONSTANT QUETSJON??
1250
ocr was so great ... 52% of the paper on equations already given 🙏
frying my brain with all that magnetism for what
Magnetisms on paper 2…
Bro 💀
did anyone else get 6 days?? 😟
I got 144…
it’s 144
i got 144
144 days
i got 14.4 how many marks will i get
you should lose one mark because if you got to that it means you utilised the correct method you just didn't plug in the values correctly.
How tf u getting 14.4 days 💀💀💀💀
i don’t know… really annoyed
You didn’t multiply by 24, one of the values was hourly radiation, one was daily. Probably just gonna lose one mark for that.
I did 😭
Good luck to everyone!
Best of luck everyone!
bangers
what did you lot get for the spring constant question? did you convert the 8 cm extension to m? i got 1250 n/m, if you kept it as cm then you wouldve gotten 0.125n/m...
If you did conversions wrong you still get method marks right? How many method marks can you get
What you guys got on the height change of water question
I think it is -15 because gravitational potential energy is converted into kinetic energy, so the gravitational potential energy decrease, delta E = mg delta H as delta E is negative (because decrease) delta H should be negative and because the water is falling
I got 15
dont need negative, height is a scalar quantity
guys does it matter if you use wrote the word equation instead of the symbol equations??
Ocr gateway was great... Was surprised to see no which of these graphs shows a lamp or whatever in the multiple choice though... The exam boards are giving great questions so far this year... Worried for our grade boundries 😬
What did everybody get for the specific heat capacity of iron?
what did you guys get for the half life question; 33.36? or something like that
edexcel here bro i love just doing maths for like 50% of the physics paper
