What should be the revision strategy for the JEE Main exam?

Here are some ways to study for the JEE Main.
Don’t just stick to reading theories when you’re getting ready.
Review the course outline as soon as you can, and then start answering questions.
First, finish your NCERT books, and then go back and review your other books.
Try to come up with as many mocks as possible.
Keep in touch with your teachers and ask them any questions you have.
Make a formula sheet for each chapter and go over it at least once a day.
Also, come up with a plan for how you will answer the questions on the test.

What is JEE Main?

The National Testing Agency gives the JEE Main test to students who want to go to India’s best engineering colleges for their first year of college. It is the first part of the IIT Joint Entrance Examination. It takes place over two sessions. Either January or April is a good time to take the test. You can take this test to get into IITs, CFITs, NITs, and other technical schools funded by the government. Also, the top 250,000 students from JEE Main can apply for JEE Advanced.

What are some tips for cracking the JEE Main?

Here are some tips that can help you pass JEE Main.
Brush up on the basics.
For JEE Main Chemistry, NCERT books are the holy grail. Read at least one time through each chapter. Practice as much as you can for Physical and Organic Chemistry until you understand the smaller topics well. Read as much as you can for Inorganic Chemistry.
Read NCERT books along with other study materials to do well in Physics.
Practice is the only way to get good grades in math. In JEE Main, speed is important.
Take as many mock tests as you can and carefully look at them. Write down the mistakes you make most often.
Last but not least, keep yourself going while you’re getting ready.
