2.2 from Oxbridge

Currently in my final year of law school at Cambridge University. Last year, I ended up getting an overall grade of 2.2 (on the cusp of a 2.1), am I doomed in terms of getting a training contract? Is there anything I could do to improve my situation?

I already have another undergraduate degree in international relations (from abroad) in which I got a 1st. Could I still apply to law firms that want a 2.1 overall given this factor?

Any advice would be appreciated!
