Hey there,

To obtain admission at IITs, you must first qualify JEE Mains and then clear JEE Advanced. For a general category male, considering cutoff at IIT Ropar since you are from Punjab, you will need to obtain a minimum rank of 2000 for CSE and around 8600 for Mech. Which is roughly around 190-200 marks and above in JEE Advanced for having a chance for admission in IITs
