# Anyone doing C4(OCR) tomrrow)15th Jan) watch

1. Thought we have a last minute discussion! I hope it will be a nice paper! I really do!

I am dreading about the integration questions, hopefully something I can cope with!!

2. it was a quite nice paper.........
does anyone want to work out a mark scheme?
3. integration by parts, i got 1
integration with working cos2x in terms of cosx first , i got (pie)/6-(root3)+1
parametric differentiation i got 3
P and Q vector question, last part i got length of OQ (5(root3))/3
4. it was nice?! I think I failed!!
5. i finished the paper in 54mins and sat there for the rest of time
6. I found it easier than past papers, but it was different from past papers aswell. I can't explain why but it was different..
7. oh dear, everyone found easy?

For parametric differentiation I got 3, but for the length of OQ I think I got root 29
9. Question 6 (MEI paper) was horrible

lol same here, fairly easy paper. only question i messed up was when vectors ABC were in a straight line.

I thought cos180, then realised the lines would be parellel, (AB and BC) hence they were a factor of 3 i believe between the values. was something like p-3=15 or something, cant remember exactly
