JeePredictorCSAB (Central Seat Allocation Board) conducts Special Rounds after JoSAA concludes for unfilled NIT+ seats. Candidates who didn't get a seat or want to upgrade can participate. Our predictor analyzes historical CSAB special round data to identify which branches and institutes typically have vacant seats and what ranks are needed.
CSAB cutoffs are ~5–20% more relaxed than JoSAA Round 6. Enter your JEE Main rank.
Predictions are based on 5-year NTA & JoSAA historical data (2020–2025) using polynomial regression and statistical interpolation. All cutoff data sourced from official JoSAA seat allocation records.
After JoSAA's 6 main rounds, CSAB conducts 1–2 special rounds for vacant NIT+, IIIT, and GFTI seats. These rounds typically have relaxed cutoffs compared to JoSAA rounds, as many candidates have already joined IITs or private colleges. If you participated in JoSAA but didn't get a satisfactory seat, CSAB Special Rounds are your next chance.
CSAB seats come from: (1) Candidates who froze seats in JoSAA but didn't report for document verification, (2) Seats that went unfilled due to lack of preference choices in later rounds, (3) Newly added seats. Typically, newer NITs and less popular branches have more CSAB seats. Top NITs CS seats rarely open in CSAB.
Participate in CSAB if your JoSAA seat was unsatisfactory or you didn't get a seat. Fill as many choices as possible. Prioritize newer NITs/IIITs where CSAB seats are more common. Historically, candidates with ranks up to 50,000 in JEE Main have gotten NIT seats through CSAB. Don't skip CSAB if you're serious about government engineering colleges.
