Hi guys, a little worried about the TSA... I cant seem to get above the low 60s in the TSA section 1...I havent really had any history with anything like it and have tried a few practices but cant really seem to get the hang of it and am just a bit worried about it

I feel like the rest of my applications is pretty strong
11A*s GCSE (state school)
4 As AS Average 95 UMS
3 A* Predictions (History, Maths, Eng lit.) and A prediction in Extended Project
extra curricular stuff like captaining football teams, grade 6 piano, chairing debating etc etc
I'd just be really gutted if it was the TSA that brought my whole application down
Basically, how important is the TSA in the application process and even if I got a fairly low score, should I be able to pull myself up with the rest of the application?
Also, if anyone was in a similar position to me and managed to improve their score or just found any resources/books etc helpful, I would very much appreciate any advice on the tsa

Thanks guys, sorry for the lengthy post and good luck with all your applications as well!
