    AQA A Level Maths Discussion Thread - 2018 Edition

    Hey guys, I thought I'd make this niiiiiice and early so we can all share how we're preparing for our Maths exams this year?

    Core 2
    Date: Wednesday 23rd May 2018
    Time: Morning
    Duration: 1 hour 30 minutes
    Days to go?: It's done! :woohoo:

    Probably the most important way to prepare for maths is to do plenty of past papers! You can find the more recent papers here and the older ones here.

    Also, Physics & Maths Tutor has some good resources for revision - everything from revision notes to questions on specific topics. You can find the Core 2 materials here.

    Good luck with the preparations everyone, let the countdown commence!

    Hi,
    I am doing revision for MPC2 AQA Maths old specification and have one question. Let`s say you worked out the full formula to find required value, next step is to put all the values in. Is it ok to use a calculator and give the required value in the next line or will you lose marks? Example:

    b^2 = a^2 + c^2 - 2*a*c*cosB
    b^2 = 13.5^2 + 9.25^2 - 2*13.5*9.25*cos 41(deg)
    b^2 = 79.32 (4sf)

    or should I replace the last line with this one:

    b^2 = 182.25 + 86.5625 - 249.75*0.7547

    Thanks

    You won't need to put that last line in, it'll be fine

    16p+q=16
    121p+q=100

    Then worked everything out. Anyone else??

    Grade boundaries will be consistent with previous years. The reason you found it a lot easier was likely because C2 seems a lot easier in comparison to c3 and c4.

    How did you do the trig question 9sinx^2 2sinxcosx = 8
    on the RHS make 8=8(sinx^2+cosx^2)
    divide everything by cosx^2
    rearrange
