Dear aspirant,
As you have mentioned that you have secured 52k rank in JEE mains and taking into consideration that you are from general category so let me tell you that it's difficult to get good nits like Jamshedpur, durgapur, Silchar,, allahabad, rourkela, Calicut.
But if you wait till csab round maybe you have chances for nit jalandhar and lower nits like Nagaland, srinagar, Arunachal Pradesh, Meghalaya, Agartala, mizoram.
