How much will my A-Level grades hold me back in a legal career?

I got slightly lower than expected in my A-levels, and got A,B,B. I thought I would have gotten an A* in psychology, or at least an A, but I ended up getting a B. The A is in business studies. My question is though, are these grades likely to hold me back much in a legal career? I’ve heard a lot of London and bigger law firms apparently have A-level entry requirements of AAB. Is this something that a lot of bigger law firms do have, especially London Law firms (as my dream is to work in a Law firm in London)? Many thanks for any help

The vast majority of Law grads dont end up working in 'big London Law firms' - and actually many don't work in Law at all.

It is unlikely that your A level grades will have a significant adverse effect on your career. Some law firms may consider A level grades in order to distinguish between candidates who all have strong academic CVs, but other firms don't consider A levels. I have been involved in recruitment for two sets of barristers' chambers and three commercial law firms, and paid no attention to A level grades.
Try to obtain a first or a good 2.1 in any subject, preferably at a university with competitive entrance standards and which requires students to work hard.
