:)!

Grade boundary for an A has been between 50-54 for the last 4 papers. This was the same difficulty so expect the same.

ONly question i really couldn't do was a 4 marker, after the R(sinx +a) where we had to find K and C.

ALso, the last question, i made a mistake on the two marker. I Forgot that it'd had made a Cube of 2x2x1/2e^4. I did it as a square. Then realised with 20 seconds to go, then tried to rush it, then got a negative answer! xD Just realised now it's because i forgot the Pi

I also struggled with the 2 2 marker Tan questions. Wasn't sure what it was asking. Did we have to put it equal to 6? DId we have to use the formulas in the book? I didn't feel the question was clear, maybe i'm just a spack! I just wrote everything i knew!

Looking back now, i'm less confident than i was when i had just come out of the exam :P

erm well you had to work out the cylinder and minus part ii. i think cylinder was 2pi(e^4) and so that minus, cant remember the answer but i think the limits were between (pi/2)e^(x^2) and 1/2 and equation that needed to be intergrated was ln2y?

In my school people struggled with the paper so might be lower than that, 62,63,64.

For an A*.

dude don't stress about this exam! Just do better in C4 and it'll be sorted :smile:

Everyone at my school struggled to finish so to be honest, I think it'll be lower grade boundaries I think!

so yeah just focus on C4 :smile:

I balls'd this up. I just did the usual intergrating formula of a bracketed of 1/n+1

I hate human error.

I didn't expand the brackets, I just did the chain rule. Don't you still get the same answer? Hope you do haha

Thanks for clearing that up for me! I think my friend said the same thing, but I didn't understand her! I've got that wrong then, haha. Oh well.

Can anyone remember what f(x) was in that 7 marker functions one? I remember what g^1(x) but not f(x).

Thought this was the best in terms of ability to do it in comparison to the last few years past papers...

I don't think I put the value of n as an integer for question 2 don't quite remember the numbers so not even sure if I got any of it lol.

How many marks out of 72 do you think you would need for an A?

I think I lost about 8 marks on the last question, 4 marks on Q8, and one or two marks elsewhere. So if 58/72 ... what would that be?
