People, relax. If your school doesn't have study leave so what? If you feel like school is of no use now, just don't come. They can't do anything about it. You will still be able to sit the exams. A lot can be done in 7 weeks. Breakdown all your courses and have checklist of the things that you need to do and prioritise. Go over your spec and then simply do questions.
Don't procrastinate about what you should do etc. Sit the **** down, and just do it
