Question: what is josaa and csab?
Answer: The basic difference is that once JoSAA completes its process of admissions for IITs, NITs and other colleges, CSAB conducts some special rounds(generally 2 rounds) to fill up the vacant seats of NITs, IIITs and other colleges (not for IITs). ... If you are not allotted any seat via JoSAA then you can switch for CSAB. 3.
