    I forgot to sub the value into the formula to get the minimum value :/ other than that I loved the paper

    Guys wasn't part a of Q9 = 1/3pi(x^2)????

    because the sector area is 1/2r^2(theta)
    which is 1/2(x^2)(2/3pi)

    = 2/6pi(x^2)
    = 1/3pi(x^2)
    ??
    i think you're right

    Easy paper - last years was slightly more difficult but then again they're all standard tbh
    But half of 9 was only accessible to the top as level students, not many in my 6th form proved it. I do further maths I got it, but the rest of my class did not, but there are only 5 of us.

    I agree with the first bit. I finished in 15 minutes and did the paper a total of 5 times but still got 74/75

    No one should be jumping off a bridge for not being as keen as us at maths
    That right there is absolute *******s, you can't finish a 75 mark paper in 15 mins, they say it's a mark a minute so you a mark like every 20 seconds?

    I have no idea how you got 120m with the wrong x value.
    Most people got 120.2 and rounded it to 120, I got 120.4 and also rounded it to 120.

    He seems like an enthusiast for maths, but also full of BS. Yes, the paper was fine, but his grade boundary predictions are unrealistic, as it still did a good job of differentiating between students, and will most likely have grade boundaries between 62-65.
    Not even some of the best further maths students or teachers would be able to finish this in 15 minutes, without making their workings/methods unclear. But whatever, why should you care about a fool.
    I hope you did well

    SOMEONE HELP FOR THE LOGS PART B

    I SEPARATED THE 2^2X+5 TO (2^X)2+5 -7(2^X) AND MADE Y=2^X

    FROM THERE I GOT Y^7-7y=0 AND SOLVED FROM THERE WILL I LOSE ALL MARKS????

    Fool? Right well you proved how ignorant you are. If you do enough practice, you can do Solomon papers in 10 minutes. But I guess most teachers don't do as much practice as the students before the exam. My teacher says she can do C1 in about 20 minutes. I agree with this. It's definitely possible considering how predictable the questions are. You don't need to think much for the majority of questions, it's just recalling methods practiced hours ago repeatedly.

    As for the grade boundaries, it's anyone's guess and your estimates are no more valid than mine. This was also based on analysis of previous years' polls and UMS whereas yours is based purely on feeling or sentiment. No offence, but you clearly aren't very intelligent.

    Do as much practice as I and you will become very quick at them because the questions are so predictable and don't vary much if you learn the techniques which can be found in the Revise C2 book. Most of my friends finish in 25-35 minutes and I'm assuming a lot of people finish in less than an hour. 15 minutes is definitely not a record. Practicing past papers will help you next time. It doesn't take a minute for every mark. Stuff such as the remainder theorem question as a whole could be done in less than a minute even though it was worth several marks

    Me!

    Definitely (9b+number)/ a number

    I agree, that 15 mark question was not really do-able to most of the students, only the top %10

    I've been in the habit of rushing maths exams ever since common entrance. It works for me and helps me to be more confident with the questions. I was expecting C2 to be hard this year based on last year's so I did A LOT of preparation yesterday. 15 minutes is perfectly fair for 9 questions which had nothing unusual apart from 10 d) being a non-integer minimum x value. As I say, most of it is regurgitation and using a calculator (get the silver Casio one and learn all of its useful functions such as storing memory and converting to time). Get the Revise C3&4 books which have every type of exam question. And read it a few hours before the exam and you will be able to get full marks in less than half an hour

    Finding a minimum? What's difficult about that? That's so easy

    for the remainder theorem question I used polynomial division and got a remainder of 5..... is that aloud??

    I think it is. It depends on the EXACT wording of the question. If it said, 'using the factor theorem, find the remainder of' or if it said just 'find the remainder'
