I am in year 11 focusing on my GCSE's this year. My current sixth form makes us do 4 AS subjects and we are then allowed to drop one ( its a grammar school) however I may decide to go to another grammar school which allows you to do 3 AS levels and 3 A levels, as long as I get A*,A*,A* in my A levels( or two A* and an A). Maths,further maths and economics are my choices will I be able to do finance/economics at LSE, UCL, warwick or imperial ? Our current system follows the new A level so we only sit an AS if we drop a subject. So if I do star with 3 subjects I don't have an AS. We also apply to Univesities based on GCSE results and I'm expected to get 10-11 A*'s. I want to be an investment banker/hedge fund manager
