Dear aspirant
At first lots of congratulations for your results .
I . I can  predict  your score is about 55 and your rank is about 1.2 to 1.5 lakh .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 and IIITs are almost negative despite of OBC category. If it was ST or SC then there might be chance for you. One thing is very important that changes in those category seats depend upon those particular category rank not on All India rank .However You can try in state level counselling and private colleges .
