Advice on revising for my exams

How can I concentrate on revising for my exams and not doing other things.
I have gcse exams in less than 1 weeks and I need to revise a lot .

How can I spend my time more on learning and doing all these thing for 2 weeks time ??

When I had to cram, I used to go to the private study booths at the library. No noise, no distractions.

im writing my end of year exams now. Immediately you come from school, change and quickly eat your lunch. Rest 4 sometime and then start by jotting down the main poits from your notes and then study them till when you think you can understand them well then you could give your parents to ask you questions and when you are reading, stay in a quiet place till you finish.
