Alevels Resits| Med&UCAT + Help/Rant

So I did my alevels this year and they went really badly -CDU it was unexpected and partly due to my chronic illness so im retaking this year because I don’t want to go into biomed. I still have to do my UCAT this week but honestly im scaredddd. I wasn’t even able to get a remark even though my psych and bio grades were realy different to what I’ve gotten so now im resitting all 3. I need any and all tips for ocr a bio and chem and also the ucat and any unis that would be good also i will be filling out extenuating circumstances forms because during y exams i would be in a lot of pain and Also the school were meant to apply for special consideration on my behalf but they ended up not doing that either because they didnt think the pain was that bad - i was in tears PLEASE WRITE ANYTHING U THINK WILL HELPPPP THANK YOUU
