Congrats on your score but let us assume that 12 lac students appeard in jee this year then as per your percentile your rank will be in between 80k to 99k. So, as per the rank there is less chance to get into top NITs, IIITs (IIT don't consider Jee mains score). But there is fair chance of getting newly opened NITs, IIITs in spot round. So, opt colleges in Josaa counselling very carefully and if you are not getting any college in any round then wait for spot round and apply for it.

Best of luck.
