Hello there fellow GCSE students!

I have started this forum so that anyone doing the additional course can know that the next ISA is going to be on temperature and rate of reaction for chemistry.

How did everyone do on the ISA ? I think mine went ok but on paper 2 I might have messed up the case studies questions becuz I didn't refer to that much data. What did u guys answer for it

I'm talking about the one on rates of reaction for concentration or temp.I believe there is only one exam set for that ISA becuz otherwise the ums conversion would be extremely hard to do

Well technically u can't redo any same exams so u have to start a new course (eg. If if u get a c in an ISA this year and u want to do an ISA again you will have to do it 2015 along with all the written exams),however there are 3 different ISA's available each year for each science course which has biol,chem and phys, so there is an ISA for each sub science and I'm talking about the unit 2 additional science chemistry ISA on rate of reactions.

T think I got case study 2 wrong because i put as temperature increased the rate of reaction doubled.I think I might have got case study 3 wrong aswell, what did you get for case study 3?
