You are correct.I think that will be where everyone will have lost the marks because I think a lot have people wouldn't have seen that it was 2 hours but I was so impressed that I saw it straight away.It was a lot easier than the may 2012 paper but I think the grade boundaries won't be as high as some people are saying I predict: A*-48 A-40 B-33 C-26 D-20 E-17.I think I may have lost a couple of marks on the one mark questions, they were hard.I am right in thinking they only asked for the units twice and that you didn't need to calculate anything using series and parallel rules-I'm pretty sure you didn't but I'm just checking.I got 18,216,00 and 79,200 too.
Doubt A* will be 48, I'd say more like 51/52

The switch was open and the voltmeter should of been in parallel instead of the ammeter.

Would I get the mark for putting the ammeter shouldn't be in a separate loop?

For the circuit one.....
1) the voltmeter was connected in series
2) the ammeter was connected in parallel

Did you have to convert the 2 hours to minutes? I remember putting something similar to those answers.

I'm going to need it. I'm pretty sure I'm the only one who put almost no effort in revision for this subject- to try and boost chemistry and biology grades of course. :facepalm:
