Special round is just like other rounds ,it held at the end of the couselling procedure. People who are already alloted with the college can apply for the special round. Last year it was held after seven rounds of counselling. There are always good changes to get a seat, because till seventh round most of the students finalize their seats. So anyone with a mains rank can apply for special round.

Spot round is held for the vacant seats available in NITs,IIITs,CFTIs. People who have didn’t get any seat till 7th round ,can apply for spot round. Anyone with a college alloted ,can’t apply for spot round.

NO , no spot round other than csab shall be there in nit agartala as it is only through councelling and csab.

Yes sagnik you are right , both spot round and special round are same. IN josaa there will be 2 rounds . 

Also for NIT Agartala there will be spot rounds . And remember spot rounds are only held if after 7th round seats are left in any college. So, if there is any seats left in nit agartala after 7th round then spot round will occur.

Thank you.
