No you dont need to give!Actually NERIST has a different pattern of admissions. There is the diploma course offered to students after 10+2 through NEE II which is the entrance exam. This course is of 2 years. Candidates can further appear for NEE III after completing their diploma to avail admissions to the degree course which will be of 2 years. The institute doesn't offer a B.Tech course directly to students after class 12. You could check their details here - https://nerist.ac.in/sites/default/files/pdf/Information%20Brochure_NEE%202017.pdf. This is the information for last year but the admission process is the same every year.
