Hey Riyanshu,
Your score is not valid enough to get admission into IIIT but you still have many options to go with. You can apply for some best private universities having their forms open. Private universities also provide best infrastructure and equally good education with government universities. You can check out the placement records before taking admission. Below are some suggested colleges -
