What did you think of the Chemistry 2CR Paper and which questions did you find difficult?, I had no idea how to draw that diagram of electrolysis, where a battery, wires, two test tubes, a solution and a weird type of apparatus was shown.

I agree! Nobody in my school who was doing the test knew what to do for it either. I reckon you'll get at least 2 marks out of 3 if you had:
i) the wires attached to the battery and to both electrodes
ii) the test tubes upside down to collect the chlorine and hydrogen
and I think the last mark could be labelling the electrolyte properly - but i can't remember the name of it.
Overall, I thought the paper was really nice and was an actual proper test of our knowledge for paper 2 - Glad there were no faradays questions!
One of the hardest questions for me would have to have been the one about creating oxygen over water in space, wasn't really sure what to put for 2 marks.
This paper was MUCH MUCH nicer than the biology paper 2.
