Good luck with your exams and you seem very committed to achieving your goals.
Some tips I have is:
1/ Make sure you revise in a clear way with creativity. Reading notes alone might not be the best thing to do. Perhaps organise it to mind maps or condense them. Read them out to yourselves to feel like you're teaching something. This way, it stays in your head well.
2/ Make sure you do practise questions to focus on exam technique and knowledge.
3/ Take breaks as it has been proven one cannot focus properly after 1 hour of full on revision. Do breaks after maybe 1 hour for 10 minutes.
That's about it, I wish you the best!
