Oxford MAT Test - 5th Nov 2014

What did you write to justify your answer? Induction was the first thing that popped to mind for me.

And yeah part iii is wrong, I think what I wrote a couple of posts up should be right though.

Instead of stating the formula, I just showed how I deduced it. Which is what they do in mark schemes. Induction is fine, just not required.

By the way, last part of 3. I don't know how MAT is marked, but you went from the thing you're meant to show to the thing you're told.

It says, given that I_n >= I, show...

Usually, you'd expect to use this fact to show the inequality they give. But, as I said, I don't know how they mark it.

Did you get beta = pi/4 + alpha/2?

Ignore that part, I assumed that BD is bisected by AC which is wrong.

By considering the angles in AXD you know that pi=pi/2+beta+(beta-alpha) I think.

These are the rough answers that I got if anyone wants to compare.



I'm not too sure about my written explanations.

This has really annoyed me, I should've put a bit more effort into Q4 (iv) and should've attempted (v), reckon I'd be comfortably in the 80s if I did.

I shudve done the end of 3 properly. I thought they wanted to derive that fp given the integral that's why I got stuck. F*** sake I think I've got into the 60/70s so I'm happy.

Well done lad, more than enough for Imperial. This is just Cambridge interview prep, anyway

I'm estimating my mark to be about 80 atm.
As I'm guessing last part of 3 would be 5 marks.
Last 2 parts of 4 to be 8 marks.
Part iii of 5, probably 2 marks, but my description wasn't perfect so probs 1 mark for me.
part iv of 5, probably 3-4 marks. I gave the correct formula, but I think I may have messed up in calculating one of them haha, so deduct like 2 marks.
Then got 1 MC wrong (I didn't read C correctly, I didn't notice the 'minimum' part).

We'll done bro. You've done great. Let's bang the bmo now. I want atleast top 250 in uk this year. Even though I gt top 100 last year I think I was lucky haha.

I kept putting 4b^2 instead of just 4 (or something like that) and couldn't see what was wrong. Gave me a massive shock knocked my confidence so I gave up on the rest if the question.. Probably cost over 10 marks! ������

What colleges are you all applying to? I'm applying to Wadham

I presume a lot of people on this thread will be taking the MAT for just Oxford or Ox+Imp, rather than just for Imperial like me. How come you people chose Oxford over Cambridge, out of interest? I'm just wondering because I originally set my sights on Oxford in like year 11, then it slowly moved over to Cambridge throughout year 12 and that is where I've applied.

My reason(s) for applying to Oxford was that I was on a gap year, found the MAT easy, didn't particularly want to have exams in the summer - so it made sense.

Or I could pretend I knew I was going to prefer pure options before I applied and how Oxford's course is more interesting if you predominantly do pure options

What sorts of things did you do on your gap year?

Had a couple of jobs, went travelling, did no maths - so pretty standard.
