Is it very silly to reapply whilst in uni in the hopes of one or two options?

What 2 options. Universities like Oxbridge, Imperial, LSE and UCL are hugely in demand and there is a strong possibility of rejection. Why didnt you go to your 2 favoured choices. Did you get rejected. Did you meet the grades. What makes you think you will get accepted this time.

LSE, didn't apply when I really should have w/ my grades and admissions test score. UCL too, except I was rejected with an excellent admissions score also.

Doing a very competitive course, applying for competitive unis. Currently at uni already in first year, but I'm very hesitant on whether I'd like to take a gap year. whilst I want to, I also do not want to end up in a place worse than my current university. I'm considering applying to university again and taking a break as soon as I can, or if I actually end up feeling like I should (still conflicted). there's only two options really I would take, if I got those. I might end up getting through a lot of this first year before an offer comes from them. but if I did get an offer, I would definitely take it from either.

is this very silly? I understand that there'd be more debt... but I'd be willing to take that in the case of either of these universities which I'd hoped to attend.

You are talking about 2 hugely competitive universities and there is no guarantee you will get offers as you already found

of course. That's why maybe I'd not take a gap year
