No A*s..is that really bad?

It seems that all the top universities want students with A*s and obviously why not? But what if you're the student who wants to get into one of these top universities but you feel you haven't got the grades because you're surrounded by As and Bs. Everyone still tells you these grades are really good, but then some of these people are the ones with the A*s.

I'm in year 11 of secondary school right now and work really hard to get the results I have. I admit I have gotten A*s before in GCSE, but in separate units and I certainly don't think I'll be able to get one overall because I already work super hard. I've already finished 3 of my GCSEs early and received 2As and 1B. The rest I'm predicted 5As and 4Bs. Don't get me wrong, I'm extremely proud of these results but I just don't feel they can get me into the uni I want to be in (and I'm not talking about Oxbridge here). Even as I browse the the stalking pages on TSR of the universities I love, all I see is A*s.

I know I still have A levels to go, and this is where I'm hoping the A*s will come in then, but can us A and B graders get into a top university with no A*s? Thank you
