CSAB (Central Seat Allocation Board) conducts special rounds after JoSAA counselling, and trust me — lots of students get amazing seats in these rounds. So don’t give up just yet. 😌

Let’s break it down nice and simple — from CSAB registration dates to login, fees, and opening-closing ranks.

🤔 What is CSAB?

CSAB (Central Seat Allocation Board) is basically the body that handles special counselling rounds for leftover seats in:

NITs
IIITs

It comes right after JoSAA ends. So if you didn’t get a seat, got a not-so-great one, or didn’t participate earlier — this is your second chance.
