Hello,

There is nothing like that. If you do like this then you will lose marks and score low in math section in JEE Mains exam.

Try to study as much as you can. Don't run to grab all at once. Take a small step and try to solve as many questions you can. This will make your basics clear. It will be a tideous work but you have to do it. There is nothing like easy as questions can come from any where. if you don't get questions from the section you have read then it will be a great loss to you. so just take guidance and prepare well. Try to increase your performance. There are many online free mock tests are available. You can take it to check yourself.

You can do it for sure. Don't panic and start practicing.

Hope it helps!
