Vacation schemes for non-law

I’m a third year non-law graduate struggling to get any work experience/vacation schemes.

I’m a third year non-law graduate and although I managed to get a weeks work experience in a small legal aid criminal law firm in my first year, I’m struggling to get any other work experience/vacation schemes. Although many have reassured me that it’s not just me, I feel that I’m at a disadvantage as I am a non-law student. Have you any advice in how I can secure any work experience coming from a non-law background?
