The time before the BITSAT is overwhelming for applicants. They cannot afford to lose any time to complete their preparation before the exam. The most important thing is to understand the BITSAT chapter-wise weightage which will help them complete the high-weightage topics in a detailed manner. BITSAT 2025 syllabus is lengthy with many topics to cover and the time is limited. Completing the topics as per the syllabus might be risky as there is not much time left for the exam and the competition is high. Moreover, it is not required to invest equal time in all the topics. Now, at this point you might be struggling to decide which subject and topics to pick first. Let’s dive into the article to find out how to start your preparation. It contains the important topics and chapter-wise weightage for BITSAT 2025.
