I can only give the generic advice that don't do things that you don't like and also not good at. Final year(s) is hard and stressful, and you don't want an "unlikable" subject wear you out, because guess what, you wouldn't enjoy revising it and wouldn't get high mark anyway! So I don't think you should transfer.
If you know 3rd/ 4th year students, ask for a scan of/ borrow their notes, answer to past paper questions, books they bought (and if they already highlighted it, great!) Ask for as many as you can, offer to pay even (don't be shy, who doesn't like helping other and also earn a quick buck?)! Summarise from those notes, criticise it like you are a professor marking. That's the cheat code that help you save hours of revising time.
