Hey there,
WOW what a lot of exams
First step- Prioritise revision to exam date
So say first exam is RE 1 and is the followed by computing the day after make sure that revision for RE 1 is done before computing

2nd Step- Revise in 30-45 min blocks with a 15 min break
Reason is that your brain will absorb more information

3rd step- PPQ are YOUR FRIEND
Its all well and good to know the info but when it comes to the exam you need to know how to answer the question- it can expose gaps in your knowledge that you need to revise and use the Mark schemes

4th Step
Try and revise whenever you can
Bring flashcards with you on the way home from school or whenever you have an appointment REALLY works

5th Step
Track your progress
There are certain subjects you are better at than others so concentrate revision on the weaker ones. Track your revision and make out a revision timetable or to do list. Tick off the topics as you complete them

Good Luck! Don't worry we have all been there with looming exams. I also had about 23 exams in a month and a bit. You'll survive but map out some free time as well you will really appreciate it

I'm doing triple science too and we've got 6 exams. Which exam board are you with?

And random question, but have you completed the 2 courseworks for Computing?
