History and Science

Bobsaleemi1998

Hi so i did my unit 2 paper in chemistry today i think i got around a E in biology and a F in Chemistry but got a B and a A in my ISA so im just wondering if i get a high C in Physics will i still be able to obtain a C in Unit 2?

Also i believe i got Two D in unit 1 and one E aswell.. will my ISA also boost that up aswell?

Another question sorry!.. maybe two more question :]

Is the ISA grade 50% of ur total GCSE science and 25% for each unit?

And my final question.. Not about Science but History.. i Did my Cold war paper last week and believe i got around a F but i got a B in my India coursework.. do i need to get 240% to obtain a c.. im also doing Edexcel Pearson.. so if i need 240% and i've already achieved around 105% (74% India and 31% Cold war) will i need 67.5% on my USA and Britain paper each? (135%)
(PS: doing AQA in science)
Thanks hope u guys reply to my Long.. yet Desperate Thread!!
