BITSAT Exam 2026 Preparation Strategy

Here are the some tips for the preparation strategy for BITSAT 2026:

1. Prioritize High-Impact Topics: Use the bitsat chapter wise weightage pdf or the tables above to plan your weekly schedule. Start with high-percentage topics like Chemical Bonding and Circles.

2. NCERT is Your Bible: For Chemistry and Biology, 90% of the questions come directly from NCERT lines. For Physics and Maths, NCERT provides the concepts, but you need additional practice for speed.

3. The 1-Minute Rule: Try to answer 130 questions in 180 minutes. If you can't answer a question in less than 75 seconds, mark it for later and go on.

4. Don't Ignore Part III: Spend at least 30 to 45 minutes per day on English and Logical Reasoning. These are "easy marks" that people who merely want to take the JEE commonly lose.
