Hi i am giving the paper in jan but have no idea how to revise any tips?
I mostly face difficulty in writing the theory part

I found the exam today quite difficult, does anyone know what an A or B would be?
And for the Vstop question there was a 5 mark question about it, what did you have to put?

It can vary from 40 to 50 for A
I think in that question we had to write about photoelectric emission

I solved past papers of last 4-5 years, today's paper was the toughest.

I agree with you i was getting over 60 and A in all of them and felt confident but this one made me think i did awful. I have no idea how it went but i needed an A and i think this exam was the hardest i ve seen, especially due to the last 3 questions.

Well i wrote about the process of the photoelectric effect i dont think ill get awarded with any of the 5 marks. Im very surprised the questions they put in, especially the LED question, the V stop, the last one of the doppler effect and the transparent plastic between the polarising filters, what did you think of them?

This wasnt the most difficult, infact it was quite easier than june 16

help meh please

please

Yes, I agree that the exam was harder than usual, but it was nit unsolvable, I even found June 2016 more difficult

Briefly about the questions:
1. LED: just a quite ordinary question. In the question with founding the resistance just counted the number of bulbs. Got resistance of something like 1500 ohms
2. V stop: a question on photoelectric effect, the general idea is that negative charge is being emitted from the plate and it becomes positive
3. Doppler effect: got approximately 56 m/s as speed of a car
4. Not sure what to wire about the transparent plastic between the polarizing filters though *((

In june 16 i got a high C and i just wanted to improve this grade but i think the LED and Vstop just made me go blanc. The rest was fine, and not that hard but those 2 questions were a lot of marcs and makes me think i ve done bad.
In coclusion i think it was tough but not super difficult. Just wanted to share this with some of you to see what you thought about it. I think an A will be around 48.

The bonds of plastic were unevenly stretched so at some points the bonds rotated the plane of polarisation of light so that it was no longer perpendicular to the plane of polarisation of the 2nd filter so light is seen. I just applied a little bit of chemistry
