JEE

ETOOS (MOTION) is the best in Kotak for IIT-JEE.

DTU and NSIT are highly reputed for civil engineering. This score is not enough to get admission in DTU or NSIT. They usually prefer students with 75% and above in 12th and more than 100 marks in JEE in case of SC category.

No, actually with this score its bit difficult for you to get admission in top colleges. So its better to try with your State entrance. Also some colleges won't accept 45% marks. They keep criteria as 50% and above.
