Hello student,
Unfortunately, I am sorry to inform you that, 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. through LEET exam. LEET exam is conducted for Diploma holders who want to get admission in B.E or B.tech courses. This is national level exam. However, you can also apply for state level exam.
I hope this helps, All the Best!
