Oxford MAT 2013/2014

No freaking way. I put B) 7 for the coefficient question. But why would they do that? Surely you can't be expected to do the whole binomial expansion and differentiate for that?

u didnt have to do that ... only luk at coefficient of x^7 .. ignore rest.

Does your MAT score have to be better for Maths & CS? As Question 6 is usually much easier than the rest of the paper each year

There was no question which required the binomial expansion. Which coefficient question are you talking about?

If it says something like:

$((x^2-x+2)^4+(x^5-x^4+x)^5)^4$

and asks for the largest power of x, just work out the largest power of x in each inside bracket. Here, on left it is x^(2x4)=x^8 and on the right it is x^(5x5)=x^25. Take the largest (here x^25) and go up one level in brackets. Here: x^(25x4)=x^100.

If there are three layers of brackets then repeat for the other side then up one more layer.

Hope this helps.

Yes, usually slightly higher. They also assured someone else here a couple of years ago that they definitely do not compare scores across different applied for degrees, not that anybody necessarily expected them to.

I know but how would we know if the coefficient of x^6 was 0 etc.? We'd have to test those out too.

Are you at Oxford? Damn it.

Also, according to my maths teacher, when providing feedback after the process is over, for the first year ever, they will NOT be releasing our MAT scores. Apparently every other admissions test (ELAT, PAT, CAT, BMAT, TSA, etc.) will still provide raw marks, but we will never get our marks back.

Anyone else heard this or have a reliable source?

I know how to do those questions, haha, but thanks.That's exactly how I did it in the question but there was a trick (ie the largest power's coefficient of was 0)...

u didnt have to do that cause next option was less than 7 ..

Oh! I'm really sorry, I thought that was what you meant. Otherwise it was just looking at which parts give x^6, etc., as you have already worked out. So sorry.

but the trick was unfair. ;(

lol .. i know I got lucky .. cause i was just curious enough to work it out when I saw less than 7.

what was the answer for q1 part (ii)? the refelction of y=sinx q?

I got y=sinx+4 or +5

I got y=sinx+4 or +5

I still think that the average will go down by a few marks. Having got over the shock, I still think that Q1 was comparatively harder than previous years.

Someone from Oxford (user gavinlowe) said that Q1 was harder on this paper than in previous years a few pages back. That being said, I felt like Q3-5 were easier than in past years, so who knows?

What did people get for the last part of question 5? I got 40095 but both my friends got around 50,000
