Okay good, yes I'm doing the old spec too. I'm studying the course via Distance Learning so I have taught all three units myself with the exception of 2 x 2 hour tutorials. Do you know any good revision sites besides GCSE Bitesize?
The only way I managed to learn is like this, in school my teacher always gets annoyed 'cause I don't write notes, but to be honest they never help me, so why waste paper? anyways THANKK YOOUU
Please can someone explain what the difference is between real and virtual images in mirrors?
Haha, I just googled that very same thing! From what I understand and from my notes:
Real images = formed when rays of light (from the same point on the object) cross, so they can be formed on a screen. Virtual images = cannot be formed on a screen, they are just where rays of light appear to have come from.

lol you couldn't take pictures of all pages in P3 textbook could you, just left my book at school... (or if not all just, all the pages on lenses/mirrors?)
IS a longitudinal wave: A wave that vibrates in a given direction? And is a Transverse wave: A wave that vibrates at a 90^ angle in a given direction (perpendicularly)

Thanks!
I'm sorry I don't have the time, I'm busy with my own revision and other things I'm afraid. All the revision sites listed in this thread are as good as, if not better, than the textbook so I would advise you to use those for your revision.

Ahhh! Less than 24 hours to go till the exam! I'm still really confused on motors, and I cant remember all the rules for mirror and lens diagrams
I've only just started to revise unit 3 today. Lesson learnt; never cram. It's doable but so stressful. I'm just working my way through the textbook and making notes, and then I'll probably complete 3 or 4 past papers later today. I agree, lenses are very confusing.
