BA Bsc switch

I received a conditional for bA Economics and Finance at Manchester and I was wondering if it was possible to switch to straight econ bsc in the first year or second year
I do maths economics law and epq

not likely, it's very hard to switch degrees once you've started uni, if you desire to switch it's better to get in contact with the uni before term starts. Although idk about this specific scenario someone with more experience may be able to help you.
