Hello Rajshree

With your mentioned rank it is highly unlikely for you to get into NITs or IIITs. You could still apply for the josaa counselling process and try your luck. But I would suggest you to try for state level engineering colleges which accept JEE main scores. You could get good colleges and your desired branch. You could use the following link to know which colleges you might get based on your scores.
