Hello,
Just need to cross your category cut-off marks fixed by JEE Mains 2018 and then, you can get admission easily here but you have to score more than 60% marks in class 12th.

For JEE, maximum weightage is taken from 12th when compared to 11th in CBSE. If your 12th score is not enough for JEE weightage then you need to score little more in JEE Mains. This could help you in getting a seat in technological colleges.
