Apply for TC with no experience

I’m a final year non-law at a London RG university. Just finished my first application cycle, made six VS applications got rejected in all of them😭. I’m applying for masters but probably will take a gap year after graduation. I’m also a international student so this is almost my last chance of applying for law firms (may still apply when I come back for masters but I might only be eligible for spring VS and TC due to visa constraints).

Feeling very worried nowadays😭 Planning to apply for some TC this summer but I have no formal legal work experience in the UK so I have no idea if that’ll work. My first and second year grades were not that good looking (approx 64-65) so I need to try really hard to bring my grades up in my final year. I got good alevels but all my alevel subjects were in science - not sure if that still counts since I’m now doing a humanities degree.

So basically I feel like I can’t help feeling worried about my future after graduation. I would be so grateful if anyone could share some tips on applying for TC with no legal experience and how to prepare for interview and ACs. Also appreciate any tips for international students. Thank you so much!
