How should I practise Accountancy so I don't blank out on adjustments in the board exam?

Accountancy is mastered by repeated written practice, not reading, so solve full questions with pen and paper daily. For adjustments in final accounts and partnership, make a one-page list of every common adjustment (outstanding expenses, prepaid, depreciation, interest on capital, drawings) with its double effect, and revise it until the dual entry is automatic. Always remember each adjustment hits two places, which is where students lose marks. Maintain a neat format with proper working notes, because in CBSE the working notes carry marks and also help you trace errors. Practise previous years' and sample papers under timed conditions so the formats become muscle memory. When stuck in the exam, write the format first and fill knowns, then handle adjustments one at a time rather than trying to do everything mentally at once.
