Hi

CSAB SFTI 2018 is conducted for admissions into the B.Tech courses offered by Self Financing Technical Institutes (SFTI). Admissions will be done according to the JEE Main scores secured by the candidates. No, you don't need to register for SFTI's seprately. Once you have registered for CSAB, it will work for special round for NITs, IIITs and GFTIs 2018 seat allotment. Secondly, wait for the second counselling were you may get better college than the alloted.

All the best.
