Preparation Strategy

Finish the textbook first — the prescribed textbook is the main source for school and board exams.
Keep a formula and definitions list — it makes last-week revision much faster.
Practise past papers — they show you the pattern questions follow.
Time your practice — attempt some papers under exam conditions.
