You have 8 weeks and 7 subjects. Give 1 week for each subject. Don't study another subject during the week you assigned for 1 subject. And proceed with the next subject when the week ends, even if you haven't finished the subject within a week. Stick to the schedule! But don't forget to do exams (especially matric and questions on textbook) regarding that specific subject during its assigned week. Use the final week to revise and do a lot of questions. Maybe you can study things you haven't study yet from every subject within the final week. GOOD LUCK!
