Dear Abhi,First of all, don't worry about your percentage. Most of the government exam eligibility percentile is 50%. My suggestion is to go for professional courses like CA CS Fashion designing, Hotel management. These are career courses, so it doesn't affect your percentile progress.

For getting into a good NIT for general and with a good branch, the least you should have is 195. Below these marks are for category students to get admitted into. Best of luck.

I suggest you to go for private colleges only or autonomous institutes of your state, if you belong from some category. There, home state quota will work and you might GET into good colleges. I suggest you to check the NIRF ranking of engineering colleges to have a reference. https://www.nirfindia.org/2018/EngineeringRanking.html
