Will my GCSE grades hold me back?

I have very good A Level grades but my GSCEs are not so good. I only managed to get three As and the rest are grade B or below.

I’m about to start my second year of a three-year law degree and am therefore looking ahead to applying for vacation scheme. I have very good A Level grades but my GSCEs are not so good. I only managed to get three As and the rest of grade B or below. Is this going to put firms off from offering me an interview?
