JEE Main

Hello Vaishu,
JEE Mains may not be important, but it's an exam that tells us our true rating. In addition, some states give admission in engineering colleges based on marks obtained in JEE Mains. If you happen to belong to such state, then it's compulsory for you.

JEE Mains paper is conducted by CBSE board not by any IIT.

Around 5000 for general category. AIR-5k.

Paper of JEE Mains is not tough but they make one part tough out of the three parts. Like last year, the paper of maths was tough. Before last year, the paper of physics was tough. It is random. We can't predict anything.

The JAC Chandigarh takes care of admissions into PEC. Generally, admissions are done not only on the basis of JEE but also on class 12th percentage. So, if you have a good percentage in class 12th, you can get direct admission on the basis of the same.
