AQA AS Core 2 maths unofficial MARK SCHEME (25/05/16)

You and I both then, you and I both. Except, I also messed up on tons of other questions.....I don't even wanna think about it.

Yeah, didnt think maths would go this badly overall in C1 and C2...did you get 88 as the answer too or something else?

C1 was ok for me but I ruined it with C2. Hopefully I'll be able to bring it back in F1....

No I got 72. My method was right but somewhere in the method I made a very silly mistake which gave me the wrong answer.

Anyway, let's try not to worry about it and focus on everything else in life instead, ruminating over it is depressing me man.

Yeah I think im wrong a lot of people got 13...hopefully I will get atleast 1 mark for some sort of working out

depends on how u rounded your answers in the previous questions bfore as if u rounded area of triangle and used the answer to 3.s.f like the questions stated youwuld get a lower or higher answer so if you have a close but not exactly the same answer as everybody else may not b qwrong

For integration questions does it matter if you forget to put '+ C' at the end because I can't remember whether I did or not?

Yeah it will matter I'm fairly sure sorry!

If you look back at integration questions on mark schemes you'll be able to see whether the lack of + C was penalised cause it might not

I think we're wrong, sadly... do you reckon we could still get 2/3 marks for method somehow?

Im actually not sure anymore what i put as my final answer. I mean my method was right dividing the area of triangle and finding R and then using that and theta R to find perimeter. If you did the same thing let's just both hope we pick up few marks.

Im sure you did but seen as the question was the first (hence supposed to be the easiest and catering to the most people) plus on most previous mark schemes they have put "condemn no '+c'" so im lik 80% sure it should be fine either way :smile:

Can you upload a proper mark scheme like you did with core 1?
