HELP!!! Really worried about my A-Level Maths resit next month

I was only a few marks of an A last year and i really need an A to meet my offer criteria for my chosen uni course. I haven't revised as much as i probably should have at this point (started in March but it's been on and off) and now i'm extremely anxious because if i don't get this A then i'm genuinely screwed. My family spent lots of money so i can resit privately so i don't wanna mess this up as it will cause a lot of drama and i also really want to get into uni this year. Is it possible to turn this around in the next few weeks?
I have started doing practice and past papers now in exam conditions and stuff and i'm making a revision timetable as we speak (i can handle 6 - 8 hours a day as i'm on a gap year wth no job atm ).
Any actual advice would be greatly appreciated rn because i feel like i'm gonna spiral. Thanks in advance
Edit: Oh my days...i must change my username 🙃

I started studying for my actual A levels a month before the first test date. I found that burnout is really something you should be wary of. Maths could be the most therapeutic of exams especially if you know what you are doing. I think I only started to learn effectively knowing how I would approach the paper first. I became familiar with how to use the formula booklet, how to make the best use of my graphing calculator, and how to approach questions in an orderly manner. Did a week of revision by simply going through old lesson materials and really working on my weak units (differentiation, trig, and integration). Then I started doing around 2-3 PPQs a day with instrumental music. Spacing out your revision I think could help. I did 1 paper after breakfast and usually one at night. Make sure to give yourself some rest time in between to keep yourself sane (idk go for a walk, read a book, eat something you like). I think approaching maths with a clear and relaxed mind = useful. Remember that exam conditions still means you could take a bathroom/water break.
Here are a few tips I used (I too was shy of the A* grade boundary by a couple of marks):

Hi @simonghostriley ,
I understanding that revision could be stressful. I remember sitting for my A-level Mathematics . I’d suggest that as you are already doing to create a revision schedule, try to focus on the areas that you don’t understand or tend to lost the most marks. Review the format of the exam paper and learn how to understand the mark scheme so you know exactly were the marks are going.
Practicing questions mainly on the topic areas of weakness. As well as knowing the weighting of each section in the exam, Stats, Mechanics and Core Mathematics.
Wishing you the best with your upcoming exam.
