1. Will I get a carry foward error for geeting the wrong value for lamba in the intergration question?
2. 7a k= -8.5
3. (Original post by fefssdf)
no I've seen on serval mark schemes where it says A1 ( with or without '+c' )
thank you phew
4. (Original post by Christoph987)
the volume of the cylinder was 544pi i think
Wasn't the radius 8 and the height 8 as well
5. (Original post by YZ31618)
3b) 4marks
4b) 3marks
7b) 2marks
Are you sure？what about 6d？which question is to fine the rotated volume？
6. How many marks for each question?

i think that question probably is 7c) and which takes 4 marks
8. marks per q.?
9. (Original post by stephaniechan)
thank you phew
too many people would lose a mark otherwise and its not really fair
10. Marks for 4a? And marks lost for doing t in terms of x? I imagine all of them but not sure; I integrated correctly
11. Is 63 in C3 and 73 in C4 enough to get an A* :/
12. (Original post by BinaryJava)
Wasn't the radius 8 and the height 8 as well
the radius was 8 and the hieght was 17/2
13. (Original post by dr-jekyll)
the last part was 5. the one before that was 2 i think
okay, cheers
14. Which question was the 15 marker on integration ?
15. (Original post by fefssdf)
Did anyone else flop c3 but ace c4...
61ish in c3
75 c4..
16. If i got the implicit differentiation wrong, how many marks would i lose? (Considering ecf)
17. (Original post by YZ31618)

omg！Is there a （c）in question7？Do you still remember the mark for 6d？Thanks a lot：）
18. Mattematics Can you tell me how many marks I will get for this:
So when working out costheta, I somehow got 15/20, and then I did 1/2absinc using the value of theta from that part, so I got like 2.65. Out of the 5 marks for the 2 parts, how many will I get? Because I believe I should get ecf marks.

Uuuh, I'd recommend looking at past questions and seeing what the marks are awarded for. If I had to guess you'd lose both for the costheta and perhaps get 1 or 2 ecf for the second part.

emmm... i think there don't have any 6d) question.
I remembered that q6 is about the integration
