    this might seem like a stupid question, but are you allowed a ruler in the exam? As far as I know, you can take a pen and compass, but a ruler has never been stated.

    You're putting 60 degrees in wrong - specifically I think you're not squaring sqrt(3)/2 to 3/4.
    You are right!
    Oh my god that was stupid.
    Thankyou

    Is 81 a competitive score for MAT? I saw from its official website that the average mark of successful applicants is 70 something, but since my grades are not that good, would I need a 90 to secure a place ( I missed 10 marks due to a mistake in addition )? Also when should I do the 2015 paper? Are there other questions with difficulty and style similar to later MATs? Coz i know the earlier ones are easy...

    What graphs? Do you mean the lines x+y = constant, and curves xy = constant?

    You can see from them how x+y increases. The largest value x+y can take is the value taken on the last line to intersect Q.

    Congrats, those are really good marks.

    For more recent exams (I believe 2010 onwards?), there are examiner reports on the website, below the test solutions. They give you a breakdown of how many applications and offers were made to each course.

    In a few of those (including the 2014 paper), there's a graph showing bands of scores (e.g 50-59, 60-69), how many people got that score, and whether they got an offer, got interviewed but didn't get an offer, or didn't get an interview.

    For 2014, around 55-60 people got between 80 and 89 (and 50 got between 90 and 100). For those getting between 80 and 89, all of them were interviewed, and around 40 of them were given offers (and around 40 getting 90-100 got offers as well).

    In short, you've got a really good chance of getting a place with a score of 81 in 2014. But it's not guaranteed - there's quite a few people getting 90+ that didn't get a place, and even somebody who got between 30-39 got a place. Really, it depends on how low grades you're talking about, and what qualification they are. But with that sort of score it's pretty likely you'll get an interview at least.

    For doing the 2015 paper, I'd maybe do it a week or two before the exam. That gives you time to evaluate where you've done well, and to really understand where you've gone wrong. 2015 was seen to be a very difficult paper, so it'll be really good preparation for whatever comes up this year.

    I'm joining the thread. To say I am frightened by the test would be an exaggeration, but I am worried as I have not studied everything I need for it. Keep in mind I found out I need to take this exam in mid-September. Are you all applying to Oxford?

    But how abt if i am applying for imperial? R there similar stats? Maybe i overlooked but i cant rly find it. Also, imperial didnt specify the minimum grade requirement include math or not coz I am taking HKDSE. Does anyone know the ans? Thx a lot

    sorry forgot to specify. i think i get the x+y graph part how it corresponds to the y-intercept hence i guess the max would be the last line of gradient -1 that touches the quarter of the circle? what i dont really get is the next few graphs and the corresponding questions.

    Yes, the bold is right.

    Well the next ones are hyperbolae, can you sketch those?

    And if you think about it you only need those hyperbolae to answer the rest of the second part.

    yeah i've managed to sketch those. I'll probably have a go at it again later when i'm back. Thank you very much, sorry for the trouble!

    I did the MAT 2014 paper and on question 1, part (j), I was confused about why \displaystyle 3x^2\int_{-1}^1 f(t) dt can be integrated to \left[x^3]_{-1}^1 \int_{-1}^1 f(x) du  . In fact, the entirety of the answer confuses me, really. Can anyone explain it to me in a simpler way than the Oxford solutions do?

    Actually, Oxford's solution is quite trivial except that it didn't explicitly specify that
    \displaystyle\int_{-1}^1 f(t) dt is a constant (but it shouldn't be hard to deduce that), hence the integral can be treated as a number when integrating.

    There's a couple of typos in the solutions - the integrand should read f(u)du or f(x)dx.

    Yes, I did think \displaystyle\int_{-1}^1 f(t) dt was just a number so I replaced the last term with 3ax^2. But this will just integrate to ax^3 - I don't see the connection with \displaystyle\int_{-1}^1 f(x) dx.

    But you didn't put the limits for x in.
