# AQA A2 Mathematics MPC4 Core 4 - 9th June 2015 [Discussion & unofficial markscheme] watch

1. NO I just realised I didn't sub in x=0 and t=0 on q 8)a)
Had 20 mins left at the end too!!!! ARGHH
How many marks do you think I lost for that??
2. (Original post by Oraeng)
only just had a chance to look at tsr for the unofficial mark scheme and it seems to be down... do you know when it will be up or are there any others out there??
You can check my model solutions

Much better thank you! I seem to agree with everything there (except 8a which I 100% got wrong) - great model solutions.

0.
6. ****. For the vectors where you find c I subbed in -4 instead of 4 as lambda... I did everything correctly and the method for the next part was also 100% correct ... I just applied a negative sign to the 4 and therefore got a completely different c coordinate which was (-9,-2,18) ... Will I just lose accuracy marks and will I gain follow up marks for method on the next part? (
7. How much ums would 55 on C3 and C4 get and 67 marks on Stats get me

I had a look at the June 14 paper and it says there is 1 mark for finding c and 1 mark for the correct final answer so fingers crossed only 2 marks lost

Hi! Love the work, I'm confident on everything except the formulation of a differential equation and the final trig question (not the parametric one).

Your +C in your differential equation solution, was that meant to be +1?

11. Sorry about the mark scene guys - it mucked up. After my physics exam on Thursday I'll rewrite it in latex. For now, an older version has been restored.

Erm, I think I got around 73/74 in Core 3 and 64/65 in Core 4. If that's enough for an A* overall is another matter :/

Don't be upset! Focus on today and your other exams! You haven't seen the boundaries yet!!

Easily! What about 73 in Core 3 and 65 in Core 4?
