    Just to make sure for the first integration question for 6 marks was i completely wrong in differentiating thr bottom of the fraction and then Integrating to give 1/3ln of something?

    I think I got 67/75 in C3 and 71/75 in C4. How close do you think this would be to an A*

    I laughed more than I should have at that bit. I am a terrible person. :getmecoat:

    Good luck though
    Haha don't worry. Hopefully it's still a strong A and I have A*s in Bio and Chem to meet my offer!

    you know for the implicit differentiation question part (b) i got the right gradient but then found the incorrect normal , i used -(22+pi)/8 and followed it through, so i got the right gradient but the wrong normal and subsequently the wrong values for a,b,c,d. What marks would i get if any?
    how many marks was it out of the a b c d question. maybe 3 method marks

    what do people predict M1 C3 and C4 boundaries to be?
    I reckon M1-58 for 80 ums, C3- 61 for 80 ums and 65/66 for 90 ums, C4- 64/63 for 80 ums and 70/69 for 90 ums

    Should be an A*. It's 90% UMS overall. C4 generally tends to be higher boundaries at about 65-68 and c3 is generally between 63+. I'd say your pretty secure great job!!!

    that's what i think i got ..yh, basically because it's not going to be 180 for C3 and C4 which is the prerequisite...

    sooo annoying because i have worked so hard for this, and did not expect to be so disappointed with maths after these two years

    Thats fine though because you will have just dropped 1 mark. Rather than a possible 8 marks on the trapezium Q. I definitely got 2 values for the two parts to the question, but I dont know how I could have gone wrong. Hopefully I will pick up at least 3 method marks and get 70/75. So if i got 65 in C3 and 70 in this, I may be VERY close to the A* boundary. We will see.

    what if I got 75/75 in C4 and 61/75 in C3, A*?

    coz for last yr, 59 was an A and the difficulty and length is comparable to this year's, also for 2014 it was 60 for an A but obviously look at the paper it was easier...so maybe i will jsut scrap an A*?

    70/75 in C3, 69/75 in C4, enough for an average of 90 UMS?
