Unit C is out of 200 UMS. So 156 would be between B to A
Oh sorry, did you mean marks? ( not ums) it changes every year according to the difficulty of the exam. For the unit b exam in January, it was only 38/60 for an A* and 30/60 for an A. So maybe for an A in this exam you would need 70% ish, but that's just a guess.
i ended up with 4x-15 over (x-2)(x-3) (or something) on the last question
i multiplied the denominators and numerator by opposite denominator ect to get the same denominator - i think thats what you do? then subtracted the top numbers
I found that 2 hours was plenty of time! Loads of people in the exam was finished with 45 minutes to spare, even after checking our answers
Like Whoopli said: x+5/x-2 minus x/x-3
I finished after an hour and 10 minutes, I think I was the first to finish! I just looked up, and everyone including the foundation people was still writing!
And for the last question, I got 4x-15 over x^2-5x+6 :')

That's what I got, apart from that I multiplied out the brackets at the bottom, I think both ways are right

For the last question i got -15 over (x-2)(x-3) [i think] the 2x on the left was a plus because you multiply out then simplify so it made it 2x-2x so no x was there. Well thats what my teacher said afterwards
