Which is best ?

Hiya. So I’m not sure what route to take in terms of uni so I’d like some advice. I decided after starting uni (ucl) to take a gap year and reevaluate my options. Would it be better to go study law at uni like (ie Royal Holloway) or continue my studies at ucl under “politics sociology and Eastern European studies” then decide to to the conversion after. I have no idea what I want to do later on so I’m not sure which route to take and I’m also conflicted on whether it’s best to do a degree in a more prestigious uni then the convert (even if not) or stick to law at Holloway as law is a vast major anyway and I can figure out my job title later. Would it put me at a disadvantage to go rholloway for law? Is it best to stick to a more prestigious uni regardless of degree?? I’m very confused and need some adviceee. Thank uuuu.
