Dear Aspirant

At first lots of congratulations for your results .
I .According to trends of previous years and this year's JEE MAIN cut off I am afraid to inform you that your chances of getting admission into colleges NITs , GFTIs and IIT's are almost negative. However You can try in state level counselling and private colleges .One thing is important that admission in OBC  category entirey depends upon that particular category rank , not the All India rank. Some good private colleges are

Amity School of Engineering, Noida
Amrita Vishwa Vidyapeetham, Coimbatore
Kalinga Institute of Industrial Technology, BhubaneswarBirla Institute of Technology, Mesra
Birla Institute of Technology and Science, Pilani
Walchand College of Engineering, Sangli
Vignan's Foundation for Science Technology and Research, GunturVel Tech Rangarajan Dr Sagunthala R and D Institute of Science and Technology, Chennai
