Was the constant positive or negative pi

they'll be low but that low?


They do seem too low in my mind. At a guess an A* in c3 will be 58-62 and an A* in C4 will be 59-64

What do you guys think Full UMS will be?


67, based on last year's boundaries

What was f(x) in the show that question.
any unofficial marscheme

It was positive but less than 1 hence the decrease in mass
Unofficial markscheme yet anyone?
I messed up the coefficients in the first question so I got a wrong answer, do you think I'll get a nice ecf only few marks lost?

Btw did anyone get 1/3 and 5/3 for the values of lambda in the vector question?

Thanks man

2root(x-1), I think.


**** sake; I needed extra paper so when I copied it over I think I messed up and wrote root(1-2x) idk why; ill probs only get 1/2 for that question. So im down to a goddamn 68

positive pi on the f(x) side

Ah ok thanks anyway!!
how were you meant to do the vector question

Anyone else run out of time? I didn't even get a chance to attempt Question 7 and 8 properly :frown:

Same here, I get extra time and dropped a good 20 marks bc of time management which is pretty gutting as this paper was relatively nice, especially compared to C3, so any chance I had of getting a good grade is fully down the toilet 💔

Did anyone get -3ycos3y +sin3y=1/6tan(1.5x)+ whatever c was which I can't recall

Depends which side of the differential equation you put the +C on. If you put it on the left, then it was -pi, on the right is +pi. Either will be acceptable so long as it was the correct sign on the correct side..
