If you do not have any shortcuts, create your own and use them frequently to get into the habit. Also, make sure you have a list of JEE Main important formulas that are handy and readily available to revise.

1. While attempting numerical problems, try to round off the data given or being used, so that you can easily calculate and arrive at an approximate solution that will be closer to any option provided in the questions.

2. If you do not get the correct answer to a numerical problem on the first attempt, then try to calculate the entire sum. Make sure you practice this technique.

3. Related to the real-life problems based on concepts, it will be much easier to analyze any given problem.

4. Revision is a must. Revise as much as possible and try to make a timetable to fit the JEE Main high-scoring chapters or topics.

5. Anticipate the mistakes you often make and practice enough to get them corrected before the exam.

Hello

The JEE syllabus mainly covers Physics, Chemistry, and Math from NCERT Class 11 and 12.
You should follow NCERT first because it builds the strongest foundation for all three subjects.
For a deeper understanding, use books like H.C. Verma (Physics), Cengage (Maths), and O.P. Tandon / M.S. Chouhan (Chemistry).
For practice, solve JEE Main PYQs to understand the exam pattern.

You can check the updated syllabus of JEE mains from here: SYLLABUS.

Hello,

You should select Jharkhand for the JEE Mains application form because you will be reappearing in the exam as a private candidate in Jharkhand. The state you will be appearing in and your passing year are what you should fill in your JEE Mains application form, but not your 12th class state.

Hope it helps!!!

It's a very good choice to aim for IIT, for getting admission in IIT you must take pure mathematics as it teach you more concept than applied which help to get more score in JEE Mains and Advanced.

You should practice more harder than yo0u do in your class 11.
