I made some really stupid mistakes and I'm a bit worried about it.
I wrote down what to put in the calculator for the 3.0 X10^9/(3.0X10^8)^2
But then I forgot to square the bottom one!!! So mad at myself for that.
Anyway what did anyone put for the Usain Bolt one for at what point was he accelerating the most at?
His acceleration was greatest between 2-3 seconds because there was a slight steeper slope there. Anything before 2 was a constant speed, and after 3 he started to slow slightly.

How much will I get penalised for not mentioning a filament as a resistor?
The filament is actually a resistor so for OCR you may have lost the oppurtunity to gain marks by not mentioning that. However, if you had a good explanation as to why the filament was hot, then it would be fine e.g electrons colliding in the fixed lattice of the filament causes heat.
A better paper than last year by far. I think I've got upwards of 50, but I shouldn't count my chickens. I should have got a B at least which is all I need for my sixth form place.
Yeah, that's what I got How did you find the exam? You seem to have done well
Well I thought the exam overall was easy. Atleast, easier than what they could have asked. The six marks went fine, and the calculations weren't too complex either. Well thats just me because I revised.

Same here, I think it was a lot kinder than past papers and the stuff they could have asked in p5 I was quite shocked going through it :/ I hate physics calculations though -_- and they could have made the graph ones a lot harder as well and could have put in a lot more morphed data and how science works questions
