The BITSAT 2022 Physics preparation tips, topic-wise weightage and the important topics have been discussed here. Check out the subject analysis below.

BITSAT Physics Topic-Wise Weightage & List of Important Topics

BITSAT is regarded as one of the toughest engineering entrance exams after JEE Main. Birla Institute of Technology and Science Aptitude Test (BITSAT) is an all-India-based admission entrance examination to the 3 BITS (Birla Institute of Technology and Science) of Pilani, Goa & Hyderabad. BITSAT will be conducted in two sessions from June 20 to 26 and July 22 to 26 2022.  The mode of exam is online and around 3 lakhs+ students apply every year. Preparing for BITSAT 2022 Physics is a challenging task as the syllabus is vast. However, if you are already preparing for JEE Main, it is easy to crack BITSAT with a good score. On this page, a detailed analysis has been made on the topic-wise weightage of BITSAT 2022 Physics along with the list of most important topics.

BITSAT Preparation Tips 2022

  • The aspirants have to divide the time equally for all the subjects in the syllabus. Wasting of time should not be done by the students in searching for the contents of the subject.

  • Reading and referring to too many books should not be done. Referring to a few selected relevant books is considered to be the smartest move.

  • Practising the BITSAT previous years' question is necessary for the students to understand the relevant topics and important questions.

  • The marking scheme should be kept in mind, the students must attend to the questions that they are sure of, and attempt the other questions later keeping the negative marking scheme in mind.

  • Revising the topics is very important. Students should make their notes, bullet points so that they are handy to them whenever there is an urgent need for a topic.

*Going through the previous years' question papers is highly recommended*
