| 4 | Time yourself chapter-wise (e.g., 20–25 minutes for 20 questions). |
| 5 | Start slow to focus on accuracy. |
| 6 | Once accuracy is above 90%, work on reducing time per question gradually. |
Ques. Are there any chapters that students usually ignore but often appear in BITSAT?
Ans. Yes. Some topics from organic chemistry reactions, coordination compounds, vectors (math), and semiconductors (physics) are sometimes neglected, but appear in the exam. Don’t skip them completely.
