Is it good to join NERIST after 10th?

It will be more beneficial if you join NERIST after class 10th than after 12th because the first 2 semesters will cover the syllabus from 11th and 12th Physics, Chemistry, and Maths as well.

Apart from the technical and theoretical knowledge, proper exposure will be offered. Civil students are taught courses like surveying, construction, building construction, water supply engineering. These are mostly taught in the 3rd and 4th semesters. By the end of the 5th semester, you will get a lot of exposure equivalent to class 12th. 

Overall NERIST is good, considering infrastructure, facilities provided and events held. The only thing that could be improved is the quality of the food. They can try making it more hygienic.
