I would suggest not to concentrate more on the cheaper colleges. I agree, these days, the cost of education is very high. You cannot get affordable and best colleges together. The cheaper colleges are not good in terms of faculty campus and placements. The expensive ones are much better.
You can go for DU and JMI colleges in Delhi. They have comparatively lesser fee structure as compared to the private one.

Graphic Era, DIT, Uttaranchal Institute Of Technology, College of Engineering, Roorkee are some good colleges according to your rank and marks.

As I am a student of Dehradun campus, I find the place very peaceful. The college is situated in an area which is away from the city and provides the perfect conditions to have a complete learning experience. This campus helps you to develop new perspective about ones career and towards his life. This place has surely made a difference in my life. Just imagine yourself learning at the foothills of Himalaya.

Kindly contact the colleges directly for the JEE Mains cut-off for the current year. I hope this answers your question to your satisfaction. If you have any further questions, kindly revert.

For general candidate (according to last year) the cutoff marks in JEE Mains is 100, while for ST candidates it is 48 marks. The expected cutoff for this year may be the same. So, you may not qualify this year. There is no criteria of class 12th percentage in deciding all India ranks.
