Transferring after foundation year

In September this year I'll be studying Business, Management and economics (foundation year) at Sussex

Is it possible to transfer to a top 15 university and do Politics, philosophy and economics if I get a 80+ overall percentage grade?

Well, it can be either way like you might get it or not. I did a foundation programme last year and it didn't really matter to some universities. They just took it as a regular qualification. And if you want to change the university, be wise with it. Otherwise, you might've to regret what I did.

What overall percentage did you get in your foundation year? What foundation year course did you do? And who did you apply to and what were their responses?
