@@photoballa Hi, could you help me? I was wondering how thorough I should mark it? Should I just watch a video walkthrough while marking and boom move on to the next paper or should I annotate?? I know this is a “competition” but it would be appreciated 😢
i have maths and further maths tomorrow and day after, was just thinking now is a good time to get ahead on paper 3 revision and i see this, absolute lifesaver!
Hello Sir. Your videos are a blessing. Every ambitious physicist at my college watches your videos religiously. Thank you for saving our physics grades.
I have completely lost the will to revise at this point. I have just had enough. I don’t even care about meeting my offer anymore. I am so burned out and sick of all this.
0:25 I think this has really been the focus this year. Not much of the spec has come up in the papers all things considered, but there's been a LOT of application, especially in unfamiliar ways. I wouldn't be surprised if they lean more into this in the future.

impossible to predict, in the past they are lower many of the years. But my best advice would be to forget about grade boundaries in preparation and focus on scoring every mark and focus on the microdetail of what bit of physics will get you to a higher grade.
Enjoy the physics that you are doing, if you have not scored well on any progression exams - tackle any gaps over the summer. I will be doing lots of useful entrance exam stuff after the last Y13 exam too : )
@@zhelyo_physics I am tryna get a A* in paper 3(unrealistic I know), except for ppq, what else can I do that can massively boost my chances. I do AQA. Are the olympiads paper something I should do?
I do aqa, and oh boy the past papers are horrible. i have a math and further math exams in the afternoon. But i am gonna tevise paper 3 before those exams
thank you so much for the comment! It is definitely on the list, but the summaries sadly take a crazy amount of time to make and I won't be able to do it before the exam. Good luck in preparation! You got this!
hi z physics please do this question for me it will be easy for u lol it was a uncertainty question that came up on aqa chem - it said pipette has uncertainty of 25cm + 0.05cm, burette has uncertainty of 24.5 + 0.05cm, find total percentage uncertainty of pipette and burette would u add the absolute uncertainties then find percentage unc of that - 25 + 24.5 to get 49.5, then do 0.05 + 0.15 to get 0.2 ,then do 0.2/49.5 x 100 to get 0.40404 = 0.4 or add the individual percentage uncertainties - (0.05/25 x 100) + (0.15/24.5 x 100) to get 0.81
bearing in mind your video said when adding values add absolute uncertainty and when multiplying values add percentage uncertainty . in the question we arent multiplying so i thought we shouldnt add percentage unc and the answer is 0.4 not 0.81
I will have a go! I am also filming a crazy hard question from the Asian physics olympiad this weekend too. Which questions should I have a go at from the JEE?
@@zhelyo_physics your welcome. Controversial problem are very fun to solve. I remember sitting on a hard chair and solving that question after using my brain for 5:30 hr long sitting in my exam centre . 😂But still i got wrong.

i havent done a single paper 3 in my entire 2 years of physics and i have 2 days left.
each is around 1 hour 30, so doable to make massive progress. You got this!
Same
Bruh i did the same for paper 1 and paper and did them all for paper 1,2 lets see what i get i expect an a
same its concerning

good luck on all those! : )
Close now, time to close this off on a win, thanks for all the help! Hopefully I get an A and don’t have to retake! Best wishes!
thanks a lot! Good luck!
Wait, is there retake available if we need to and when?
@@user-lb5ys8tm2o i think from now you have to do retakes next june again

thank you so much for the comment! This is so much appreciated!
Give me your tip on how to prepare for paper 3! : ) Good luck everyone!
eat yummy food and understand the concepts
@@RakuyoHITS excellent life advice in general

@AlexTheSB2 time are hard man… best of luck to you I’m sure you can do it
how did you do? how are you? are you still burnt out? I'm giving my AS p3 exam in 2 days lmao
@alexthesb2241 how did it go

i want to say thanks sir for everything, you really helped me in my revision and these videos deserve way more views
anytime! thanks a lot for the comment!

will solve it this weekend, thanks! : )
I’m getting like 13~20 from past papers I’m so worried bruh nothing in paper 3 makes sense
Persevere with it. Everyone finds it hard initially but each problem will teach you something.
@@zhelyo_physics the grade boundaries are really low though for p3 isn’t it?

i do ocr i'm so lost what do I even do? I feel like i've forgotten everything from paper 1
You've not! You got this, good luck!
Sir, it's Practicle paper do they provide the apparatus etc to solve questions or we have to do it on our own
Every question is different. Both are possible.
Is there any tips you have for year 13 (currently in year 12)?
Enjoy the physics that you are doing, if you have not scored well on any progression exams - tackle any gaps over the summer. I will be doing lots of useful entrance exam stuff after the last Y13 exam too : )
@@zhelyo_physics Thank you!
Why is absolute uncertainty in gradient [m(best) - m(worst)] rather than [m(best) - m(worst)] / 2 ?
they are essentially the same equation, it's more like the absolute value of mbest-mworst : ) Hope this helps!

Hey your videos are great and id be soooo grateful if you could make an Electronics summary video :)

@@zhelyo_physics That's totally understandable, I appreciate you taking the time to reply! Thanks :)
i dont even think ive looked at astrophysics exam questions yet my teacher finished so late😭
You can solve them all in a couple of days. Check out my astrophysics revision video too. : )
@@zhelyo_physics thank you this is my plan now!! trying to stay positive lol!

hi is there a way we could talk?
yea no shit , this came in my reccomended after my paper 3.. I'm filling for paper 2
Brother can you solve jee advanced 2023 controversial physics questions and make a video on it?
I will have a go! I am also filming a crazy hard question from the Asian physics olympiad this weekend too. Which questions should I have a go at from the JEE?
thanks for the idea, love a good physics controversial problem!

Is paper 3 mostly about experiments
depends on your exam board, solve as many as you can before the exam
@@zhelyo_physics My exam board is OCR but i will try solve as many as i can.
His smile is like Shahid Kapoor
I hate paper 3 so much
Me watching this on the way to the exam.
God bless me
good luck! Hope it goes well!
watching this 30min before p3
good luck!! Hope it goes well!
@@zhelyo_physics it went absolutely freaking great
🐐
I have 11 hours and 15 minutes left lol
hope it goes well!!
i accedently had my earphone volume on max and that intro bell killed my ears. Ain't ever gonna hear sound waves again.
Don't worry - there is a video on medical physics! I might change the intro sound effect though, thanks : )
