Would I get an offer?

I recently got interested into Computer science and software in yr12. The problem is, is that I never focused in yr11 for comp sci so I got a 3 and failed it. But in my gcses I mostly got 8s and 7s and like one or two 6s. Got an 8 in maths as well and I've seen that unis care a lot about maths for comp sci degrees rather than comp sci itself even though it's a recommended subject ofc. I just wanted to know if this would affect my offers for uni. I've went to a lot of events, residentials and programmes and stuff for my personal statement so do you think it'd be worth applying to a top uni like Imperial? I'm just annoyed with my comp sci gcse that's the only thing that's bothering me. I'm doing Bio Chem and Maths for A levels as I was initially interested in Medicine but realised I like comp sci and maths way more. I'm predicted A* in maths.
