Dear Tarun,

In order to apply for the engineering you can appear in the entrance exams like JEE (Main+Advanced) to take admission in IITs/NITs/IIITs and GFTIs.

To be eligible you should have 75% marks in your board exam or you should be in top 20 percentile for general category and 65% marks for SC/ST.

To take admission in top private colleges you can apply for BITSAT, VITEEE, Manipal, SRMJEEE and Amrita.

For your state level government colleges you can appear for your state level exam.

Good luck!!
