I'm doing those exams this May/June. I just realised that was rather unhelpful because I don't really have any notes for the ideas in context. Are you talking about the ones with the face cream/ racing cars/ Lithium batteries for cars? If so, just underline key words etc. and look at past papers.

hey yh I'm doing bio&chem retakee and i dont know what unit it is..i have no teacher to help either ;/
apparently we revise c4 for the lithium batteries for cars,
but i dont know which section to revise for the face cream one..do you?

No, I don't know either - that one was really ambiguous; it might not be any of the modules. I think it's probably B2-keeping healthy, because it talks a bit about drug trials etc.

Luckily, only 1 question in each paper will be based on these pre-release materials, but the '7s' are so hard, especially C7.

3.) Describe and explain the advantages and disadvantages of digital against analogue signals.
4.) How would you calculate:
a.) Kinetic Energy
b.) Momentum
from the speed of the car?
c.) A formula 1 car has a mass of 620 kg. Using the graph, calculate:
i.) Maximum kinetic energy reached
ii.) Maximum momentum reached
iii.) Minimum kinetic energy reached
iv.) Minimum momentum reached
5.) How does time taken to stop affect the force acting on the object that is stopping?
6.) How do crumple zones help reduce the force acting on the driver in a crash?
7.) Describe and explain at least 2 ways that the HANS device helps reduce damage to the driver in a crash?
8.) Match the keyword to the definition
