Eh Maths with Eco at UCL is probably the hardest Maths and Economics course in the country, focusing heavily on Pure Mathematics.
Application : place ratio has been around 20:1 and last yr they had to makes offers as high as AAAa so in that sense it maybe easier to get into the BSc Economics at UCL than Maths with Eco
However this yr Dr.Bowles have more flexibility over the admission but i don't know to what extent this will increase the number of intake.They have appointed 2 Mathematicions (who know Economics) and they will be teaching in the maths department some of the first yr Economics (with more emphasis on Mathematical Economics)
Good course overal, downsides would be :
1. Too much emphais on Pure Mathematics
2. Too little emphasis on Statistics (especially for BSc)
3. Simply too hard...Maths and Economics is a hard course anywhere but this one really takes the p**s
