how to prepare for the exam? so that i can get good score in mains examination

Physics

Along with some books such as Concepts of Physics by HC Verma, you should also refer NCERT books. This will help you understand the concepts in a better way. As it is a conceptual subject, you should understand the basic concepts thoroughly that will make the problem solving easier. After studying a particular topic, ensure that you solve the related problems on the same day. This will make your concepts clear and help you remember them in a better way.

Chemistry

Chemistry is a combination of concepts, theory, problems and chemical equations. Refer some good books that will help you understand the subject better. While studying a topic, you can always mark the important points so that you can refer them in future for revision purpose. You should also solve the problems related to the concepts and practice the chemical equations to remember them in a best possible manner.

Mathematics

It is the most important subject and you can only be thorough in all the topics when you keep practising the problems. When you solve the problems continuously you can create your own shortcuts and relate different topics. This will help you save time during the JEE Mains exam.

These are some of the subject wise tips for the students who are going to appear for JEE Mains. You should make a time- table and allocate time for all the subjects. You can also allocate more time for the topics in which you are weaker. This will help you finish studying the syllabus within the timeline and give you time for revision.
