Yes, what Sohan Kumar said is right. I want to add some extra information.
JEE Mains has total of 90 questions each carrying 4 marks.
Total-360 marks
And there's negative marking also 1/4 negative for 1 wrong answer.

To get a top college and your desired branch you need to have a rank below 2000 if you are an OC candidate. The score can't be told exactly because the pattern and marking system differs every year. So, you need to have minimum 40%.

From this year onwards, class 12th results do not have any weight-age in JEE Mains and Advanced exam, but you need to score a minimum of 75% if you belong to general or OBC category. It is required to get admission in IITs and NITs.

IIT and NITs are not the only good institutes for engineering, there are multiple other good options. If your JEE Mains score is not good you can still get admission in a good engineering college. In order to mitigate risk of failure in JEE, you are advised to appear for some other engineering entrance examinations.

Yes, you have to score approximately above 75% in class 12th exam to be eligible for JEE advance.
