GATE PE Marks vs Score vs Rank 2023–2026: Official Data and Calculator

GATE Petroleum Engineering is a small paper. In 2026 only 1,137 candidates appeared and 317 qualified. Small papers swing, and PE’s has: the General qualifying mark has gone 34.4 → 42.6 → 31.1 → 40 over four years, and the same 50 marks was worth a score of 468 in 2024 but 654 in 2025. This guide puts the four official reports side by side, shows why 2026’s cut-off landed exactly on 40, converts marks to score for every year, lists the official rank each score band reached, and gives you a calculator for your mock-test marks.

Two things stand out. The paper is shrinking: appeared candidates fell from 1,796 to 1,137 in three years. And the 2026 cut-off was not an easy-paper accident. The mean mark rose to 27.52, the highest of the four years, while the top-candidate average stayed at 66.67, so the middle of the field did better while the top did not pull away.

The General qualifying mark is the mean plus one standard deviation of the marks, but never below 25 and, since GATE 2025, never above 40. In 2026, μ + σ = 27.52 + 14.29 = 41.81, which the cap brought down to 40. Without the cap, the cut-off would have been close to 2024’s 42.6, which had no cap. The OBC-NCL/EWS mark is 90% of the General one and SC/ST/PwD is two-thirds, which is why they read 36 and 26.6.

PE was a single-session paper in 2023–2026, so there was no normalisation (check the 2027 schedule when it is out): your raw marks go straight into the score formula, S = 350 + 550 × (M − Mq) / (M̄t − Mq), capped at 1000. Mq is the General qualifying mark and M̄t the average of the top candidates. Because both change every year, the same marks convert to very different scores. Check: 2026’s top mark of 69 gives 350 + 550 × 29 / 26.67 = 948, the published top score.

The reports publish how many appeared candidates fell in each 10-mark band. Summing from the top gives the number at or above a mark, which is the closest thing to a rank for a given raw mark. In 2026, 50 marks put you in roughly the top 97 of 1,137; in 2024, when the paper was easier at the top, the same 50 marks was only about the top 209 of 1,770.

Each report also prints the range of All India Ranks inside each 100-point score band. Two cautions. The table is titled “ranks for qualified candidates”, but its ranks run past the qualified count (to 541 in 2026, when 317 qualified), so it covers reserved-category qualifiers below 350 and more. And because the field is small, a 100-point band can hold only a handful of ranks at the top.

Three practical rules follow from these tables. First, plan for a General cut-off near 40: two of the last three years sat at or near it, and the cap means it cannot go higher. Second, use 50 marks as a working benchmark for the stronger M.Tech rows, not a universal cut-off: on the 2026 field 50 marks was a score of 556, and IIT Madras’s PE-paper HTTA seats and IIT (ISM)’s first round closed at 542 in 2026 (our M.Tech guide has every row). Third, a score of 700 took about 57 marks in 2026 (the 700–800 band covered ranks 26–46) but 64.6 marks in 2024 (ranks 29–71), so a single year’s conversion is never a promise.
