Hi Siddharth, hope you are doing well, let me tell you the truth that with 7487 rank you can not get into your top NIT's with your desired stream like cse,ece and all. But you have good chances to get into NIT's with other streams like civil, mechanical in top NIT's like NIT Warangal, NIT Nagpur, etc. I would suggest you go for rank predictor to get to know about your admissions in detail in careers. The link for the rank predictor in jee mains is given below, kindly go through it
