Straight Maths as in BSc Mathematics (Pure Maths)? Or maths or stats or physics or finance or something???
You do econometrics at LSE rite? Why couldn't you coach him?
Is LSE econometrics as mathematical as Imperial Maths???
Btw why LSE econometrics course take in so many students??? What is the diff between your course and LSE Maths and Econs? or the flop course LSE Biz Maths and Stats (which I have the chance to switch to from my actuarial science offer)...
