Statistical model summary

→P(CR₂₀₂₆ ≥ rank) = 1 − CDF_t(df)(t)t = rank − x̄s · √(1 + 1/n)
→Safe (≥99%) -statistically significant at 1% level that 2026 closing rank ≥ your rank.
→Good (80-98%) Borderline (50-79%) Reach (<50%)
→IITs use JEE Advanced rank; NITs / IIITs / GFTIs use JEE Mains rank.
→Round tabs (R1-R6) recompute t-distribution using that round's data only.

The method

Statistically grounded rank-to-odds conversion

Not a simple count. A proper predictive model: we use a Student's t-distribution with n-1 degrees of freedom on the historical sample to predict 2026 admission probability.

Enter your rank & details

JEE Mains rank for NITs / IIITs / GFTIs. JEE Advanced for IITs. Pick category, gender, and quota.

Fit t-distribution to 5 years of cutoffs

For each program we compute sample mean x̄ and std s from 2020-2024 final-round cutoffs, then the prediction-interval t-statistic:t = rank − x̄s · √(1 + 1/n)where n = number of years of data (up to 5).

P(CR 2026 ≥ rank) at stated significance

Confidence = P(CR₂₀₂₆ ≥ rank) under a t(n−1) distribution:P = 1 − CDF_t(n−1)(t)≥ 99% → Safe · 80-98% → Good · 50-79% → Borderline · <50% → Reach. Expand any card for round-by-round tables.

≥ 99%

Safe

99% confidence the 2026 closing rank will be ≥ your rank. Statistically Safe.

80-98%

Good

High probability of admission. Strong historical backing, likely but not certain.

50-79%

Borderline

More likely to get in than not, but below the threshold for high-confidence calls.

< 50%

Reach

The model gives less than 50% probability. Admission would be historically unlikely.

Features

Everything your counselling needs

Statistical prediction model

Uses Student's t-distribution with prediction intervals, not a simple frequency count. Safe = 99% significance.

Round-by-round analysis

Switch between rounds R1-R6. Confidence is recomputed per-round from that round's data across all years.

Year-by-year breakdown

See which years your rank would have qualified, alongside the t-stat and predicted mean for full transparency.

Advanced filters

Filter by avg closing rank range, specific institutes, or branches to narrow your shortlist. Sort by college + CR.

IIT + NIT + IIIT + GFTI

Advanced rank for IITs, Mains rank for NITs/IIITs/GFTIs. Female-only seats, home-state quota, all in one place.
