Ayush considering you a general category student with your 85 marks in JEE Mains exam your AIR must be around 90,000 - 1,00,000. I am very sorry to say Ayush but with this rank, it will be very difficult for you to get admission in any of the NITs even with the state quota in your Home NIT you will not be able to get a seat in NITs. For further detail, you can check the last 2-years cut-off of all the NITs with the link given below:

But still, you have a moderate chance to get into some of the government engineering colleges running in each state by the state government and accepts JEE Mains marks for admission. You will need to look out for those colleges or if you can tell me your home state then I will help you in finding it and looking your chances of admission.

Also, with 85 marks you are eligible for JEE Advanced examination so you still have 1 more day to register yourself for the exam which is going to be held on 20th May. Do it quickly if you wish to do well in JEE Advanced examination and get admission in one of the IITs.

Feel free to ask if you have any more queries. All the best!!
