Does anyone know how many marks the last part of question 8 was? (where you use k=3), and how many marks was that whole question?
When is the unofficial mark scheme up?
Original post by lappong99
I got that but why is the question is specifying y>11/3?


3/11 you mean? and 1/3 is greater than 3/11 lol

yes, good luck! how did you find C1 and C2?
Original post by RJM1997
how come?


The conditions for an a* are:
- 80% average across AS and A2 combined
- 90% average across C3 and C4

So as long as you get an A in C2 getting higher won't per se help you get an A* unless C1 or applied went quite badly.

Need 90% average in c3/c4 for an A*. Along with 480/600 UMS overall.


Do you not need 80 UMS in C1 and C2?

this is correct i believe. i got the gradient to be -3. then gradient of tangent to be 1/3.

yeo sorry that is what i got the gradient of the radius line was -3 and then the gradient of the tangent was 1/3
Pretty sure Edexcel were high when they wrote that paper

Got 226. One of my calculators can do integration function and agree with that result so :smile:
I ended up getting something £11000 for the minimum of C...anyone know what happened? :tongue:
