You still don't see the answer? Finish off the paper and come back to the question. Still don't see the answer? Start equating the equations you half filled in. Above all USE LOGIC. Think logically. Don't break out Q=eV when you're doing a question on pressure. Make sure you understand the actual concepts of the mechanics section

Latent heat of fusion and vaporisation is very strong. freefall and f promotional to a is what will definitely come up in mechanics. Wait you could add conservation of momentum to it too.

I'd say a heat exp is pretty much guaranteed for section A, as long as the sec play nice XD

No way will i have enough time to cover all the definitions now.. A C is looking quite difficult atm. All ive done is exps, particle physics, modern physics

Can you pass by just writing down Formulas which are 3 marks and then its like 3 marks for subbing in? would you pass by doing that and just using log tables and then get like 15-20% in section A?
