NIT

In which category?

Sir as you mentioned that you have secured 180757 rank in JEE Mains accordingly you have not even clear the cut off for JEE Mains 2019 which is 76.31 percentile for obc category, so you will get very low level colleges if you apply through your JEE Mains score, try for private institutes such as srm, vit and bits.

If you belong to General category then it's not possible for you to get admission in NITs. If you belong to other category, then there might be a chance for you to get admission in lower rank NITs.

There is no school category in JEE Main. However if you belongs to SC category than you can get the following NITs.
1. NIT Jalandhar
2. NIT Hamirpur
3. NIT located in. Eastern region like NIT Arunachal Pradesh, NIT Mizoram etc.
4. NIT Calicut
5. NIT Srinagar.
