Greetings Aspirant,

I hope you are doing well. Joint Entrance Examination – Main (JEE-Main), formerly All India Engineering Entrance Examination (AIEEE), is an all India standardised computer-based test for admission to various technical undergraduate programs in engineering, architecture, and planning across India. The exam is conducted by the National Testing Agency (NTA). Admission for B.Tech, B.Arch programs in the premier technical institutes such as the National Institutes of Technology and Indian Institutes of Information Technology are based on the rank secured in the JEE-Main. Since 2021, the test is being conducted 4 times every year, spanning from January to May.

See it's all upto you 4 chapters in a day is not impossible but remember that you can clear most of the concepts in a day but what makes your marks increase are the back work you do that is solving problems, doing previous year's question etc, so if you are only talking about the concepts then yes you can complete 4 chapters in a day.

I hope this information helped you.

All the best Have a great day ahead!
