Edexcel C12 Maths (IAL-AS) 20th May 2015!!!! :)

Yep I did multiply the equation by 8 so it was 8y and c was 121 to get ax + by + c form

does anyone know what should be our minimum RAW marks for a UMS of 200/200?

Since the grade boundaries are always so low for C12 ,you don't need to get full marks in the exam itself. For January 2015, full marks in UMS was 113/125 and for June 2014 it was 103/125 since the exam was difficult. I predict full marks in UMS would be between those grades since the exam was harder than Jan 2015 and easier than June 2014 probably will be 109 or 110/125 ,but it all depends on how well students did in the exam

i think u shud get 125/125 in the C12 paper to get a ums of 200
its usually written in the grade boundaries or u can use the ums converter on the edexcel site if u wish.

p.s i jst checked for jan 2015 it was 113/125 for 200 ums
