Hello dear,
All things are based upon the level of difficulty of paper and the no. of candidates appearing in the exam.

Friend your JEE Main rank is good but due to your 12th marks you will not be able to get NITs or IITs. But you can get government colleges in your state or in India or can go for private colleges also.

I think DTU is better option but if seen according to priority list which is best
NIT Durgapur, DTU, NIT Hamirpur & Jalandhar.
In NIT, Durgapur last year closing rank was 18112 so there is less chances but if take part in JOSSA counselling carefully then there will be a chances in Durgapur otherwise DTU is better option.
