It was OK but I screwed up on some bits, lost at least 6 marks :/
On the first question did you get something like A=1 B=2 and C=3.
I really can't remember might be in different order, also what did you get for cartesian form? I was struggling on that and I got like X=3Y^2-Y so I was pretty stuck after that :/
I am really nervous that I haven't got an A though, I know that I probably did get an A for Core 3 but this felt like a B or C. Probably going to stay up tonight and wait for the answers to be uploaded :/.

Oh damn I think I got a negative number for one of a b or c. I skipped the Cartesian question didn't have a clue. The vectors question was hard, were you supposed to use the dot product formula? cos90 was 0 so what do you do then?

Yeah I think I got a negative actually, -1 for C
Then I got a weird answer for the subbed result. So that's probably two marks lost.
Vectors was fine, you needed to find lambda because CP dotted with the direction vector was zero.
But I am panicking, what do you need to get into uni?

I need a B which I think I will get, if not then there is always my insurance uni.:)

Ahh I need to get an A overall but I need to average 67 UMS in both to get it.
That's probably the worst maths exam I have done, I remember I felt the same in C2 last year but I got 82 UMS and I skipped a whole question. But this time I know I went massively wrong in some bits.
Though I have finished now :), I think I have defnetly got into my insurance which is AAB but with these things you never know.
