Dear aspirant,

According to your question and taking into consideration your rank in jee mains,it is very difficult for you to grab a seat in any good and renowned nit as the cut offs in josaa rounds are very high as per your rank.

So,by any means you have to wait till csab round for a better college.

Maybe you can grab a seat in nits like jalandhar,goa and other parallel nits as the cuts of goes low as compared to other nits in csab rounds.
