how can a diploma holder get admission in NIT's
Hello,
You are not eligible to take admission in NIT but you are eligible for IIT. Diploma holders are eligible to get direct admission in second year of B.tech or B.E.
There is no direct exam to get admission in NIT after completing a diploma course.
Hope it helps.
Good Luck!
The only way to get into a nit to pursue b.tech in any stream is by giving jee mains. So you need to apply for jee mains, and if you crack jee mains with a good rank you can get admission in a nit in any branch (apart from your diploma branch). Jee mains will be conducted for 4 times this year and the application process for first session has already ended so you can apply for the other sessions. The application process of jee mains for march session will most probably start at the end of February jee mains. For more info on jee mains, you may visit the following link:
