About Counselling Seat Probability Calculator

Last year's closing rank is the best available predictor, adjusted for changes in seats and in the applicant pool: more seats push the closing rank later, more applicants pull it earlier. The margin between your rank and the adjusted closing rank drives the probability.

Formulas

Adjusted closing rank

Adjusted = Last year's closing rank x (1 + Seat change %) / (1 + Applicant change %)

Probability

Scaled from the rank margin relative to a 15% band around the closing rank

Frequently Asked Questions

Why do closing ranks move year to year?

Because of changes in seat matrix, candidate preferences, new institutions opening and shifts in the applicant pool. Movement of 10-15% is normal.

Should I rely on a single year's closing rank?

No. Use three years of data and look at the trend and the spread, not just the most recent figure.
