- How to prepare Science for the Bihar Board exam 2027?
- Start with the chapters that carry the most marks; work the board’s real questions of each chapter and compare with the model answer; do objective questions daily; write one full paper to time every week. The Ask Medha app does exactly this in 45 minutes a day, at your pace.
