10 Physics Mistakes you shouldn't make
In this video I go through 10 mistakes you shouldn't make in your A Level Physics exam. In order to get the best grade possible, you need to understand the content as well as being able to answer the questions. However, mistakes can cost you, so watch this video and try to avoid making these common mistakes in the exam.
Thanks for watching,
Lewis

I hope other boards publish such "user-friendly" examiner reports

Usually OCR is the worst at this...

aqa has some lovely writeups
Thank you very much for this. I have been a physics teacher for 30 years and I am an A Level Examiner. I have learnt at least 3 new things by watching this video for the first time. Keep up the good work.

Thanks, I thought the way OCR did this was really good, a lot more user friendly than an examiners report. I certainly noticed things I'd not thought of and never really emphasised with my students enough.
Concepts really well explained and the handling of past papers excellent!!!
3:50 Photo-Diode & LED; the only difference is the direction of the arrows, no? I don't know what the question was so can't say what's asked. :)
'Current' isn't induced into a transformer secondary. It's VOLTAGE!

Adrian Waygood You’re quite right. At 3.25 I should have said ‘an induced pd which then causes a current’.

YES! It’s p.d
what ever students are lucky enough to be taught by you in real life have absolutely zero reason not to get A*
Does evey exam board specifically make one of these documents? I know the mistakes are universal, but I was just wondering if, say AQA, make a similar document with mistakes from last year's exams.

MrMas9 This is the first time I’ve seen such a concise summary. Often this information is contained in examiners reports which every exam board publishes. This OCR document is much more user friendly.
Why is the redshift wavelength dependent? It depends only on the velocity of emitter and observer? The wikipedia page for redshit has an image of absorption spectra where the shift in wavelength is constant for all frequencies

After some reading I think it is because cosmological redshift is distinct from doppler redshift?
Intensity isn’t that
