Yep but I don't think it is in the right form??

It was very stupid of me to put it like that but I do think it's in the right form.they asked for Ae^x. A=1 and e=(ln(e^2)/144)
Was quite good tbh, one of those papers that felt bad while doing it cos of the weird exact value answers but after checking on the calc and checking through again it was good. The substitution thing messed me up for a bit but got 2(x-2)^3/2 + 4(x-2)^1/2 or something like that?

People say this was the hardest paper ever every year.
To be frank this paper was not the hardest out of all papers that exist out there
I would say 54-57 for an A)

Would be nice if someone created a mark scheme)


I agree It was an easy paper but 8 was hard to put in exact form and 9 was written in a difficult way and challenging to write in the correct form

Technically you are right but that is pushing it imo as you can easily simplify it to (1/144)e^2

You'll lose 0/1 on what was a difficult question so I wouldn't worry.

Similar difficulty to last years paper, so alright paper overall


Last year was way easier
As an Asian, I am likely to be disowned after my parents find out the result :frown:

Edit: Friend of Asian here, I found that difficult wooo lower grade boundaries, my parents might as well be Asian the reply I got from them being told it was hardest paper out of the available online. RIPPERONI PEPPERONI

Also was there a question which was integrate from 1-8 (1/cube root 3) multiplied by lnx or am I mixing 2 questions together?

Ran out of time.

Needed an A in maths for uni...totally f***ed now.
How many marks do you think I'd lose for not writing the answer to the last question in the right form? I was running out of time so I didn't simplify it and wrote it as e^2+4ln3+2ln6 ?

Can we get a mark scheme
can u guys still remember the one which was to work out two possible angle values?
what do you guys get?
Needed an A* in maths and don't think I got an A* in either C3 or C4

Failed that

12.7 and 77.3?
Wat was the polynomial for the parametric question part (iii)????

I did the same, I just assumed i flopped the whole Q but does that simplify to the right answer?

i remember it was 2(1-x)-2(1-x)^3 so that expanded out. 2x^3-6x^2+4x

For that vector angle question i got 18.4 and 77.3?? What did other people get?
