1. What sort of questions will they ask you in the cambridge interview? My mind tends to free up when I'm being watched after beig asked a question, so any tips for me?

Thanks
2. my brother went to cambridge studying maths, and i remember him saying he was asked how to cut an orange into 3 equal amounts, onli cutting it twice.....i dnt know what the solution was
but.......you should talk to your head of year/maths teacher and they realli prepare you for the interview!!
3. Thanks Pamiyoo, any advice I get here makes me that little bit more confident about the interview!
4. Stardust, which college are you applying to?
5. For the orange question, what about finding the volume of rotation equation of y^2+x^2=r^2 and working out how to get a third of it or something along those lines
6. then you could cut the third off and halve the remaining two-thirds

Yup that works fine, would be my preferred method of approach. You could simply cut a parallel plane to the first as your second cut, from the other end of the orange, or divide it in half more conventionally .

ahah! knew i was cambridge material, pity this wasn't a natsci question
i'm also applying to trinity, good luck simba although your posts/grades suggest you'll walk it
9. A friend of mine got asked the following. This is rather horrible.

You are standing on the shore of a desert island, and looking towards another in the distance. When you hold your arm out, you thumb perfectly blocks the island from view. By taking into account the curvature of the earth (provided), how far away is the island?

I worked through it without huge problems with him the next day, but in an interview I would just have gibbered for a while.
10. sounds unpleasant
i think my blagging technique would be to start drawing a diagram
11. Don't knock it, it helps I can't do anything unless I've got something to doodle on. Even if what I'm doodling isn't anything to do with the question
12. (Original post by only nihilism)

Is that all you'd have to say? and that's a cambridge question?!

13. I don't think you'd get as much credit without doing the integration to find out how the height of the orange relates to its volume and therefore where you cut to get the third :P
14. Oooh I'm looking forward to my interview (if I get one!)
15. That's promising If I had wanted to do Maths and had known that those were potential questions I would be looking for a stout rope around now.

Same hehe have you seen the maths 'interview' on the Emmanuel website? I think it's Emmanuel anyway!

It is indeed. They showed it us on the open day there in April. That girl would be offer-standard the DoS said ;yes;

That's wonderful to hear the questions she got asked were pretty easy, I just hope if I get an interview it goes as smoothly!

Yep, I'd love it to go like that We'll see I suppose; it could be a month tomorrow

Hehe, yeah, it's exciting! Plus with the SMC on Thursday and BMO1 on 30th November, it's going to be a busy month or two maths-wise!
