100% in Cambridge

I'm in AS Level currently and since I'm planning to major in law, I was wondering how often Cambridge offers full financial aid to international students. If they do offer full scholarship, can anyone tell me what additional things I could do along with excelling in A Levels to get the full funding?

If there's anyone who has actually been accepted into Cambridge uni with a 100% financial aid, please do help. I don't want to stay where I am rn. I'm miserable. Abroad is the only escape for me.

Please.
Thank you.
