Hi student,

Council of Scientific and Industrial Research University Grants Commission National Eligibility Test (CSIR UGC NET) is a qualifying exam for Assistant Professor/Lecturers. It is conducted twice every year. This time form is to be released and exam is expected to be conducted in June. Yes, you may become an  assistant professor in IIT but for that you have to work harder as the cutoffs for IITs will be higher.

I hope this information helps you.

Good Luck!
