i. GATE Score

The GATE SCORE of a candidate is a statistical performance index in the range 0to 1000. It reflects the ability of a candidate, irrespective of the paper or year in which he/she has qualified. Candidates with same GATE SCORE from differentdisciplines and/or years can be considered to be of equal ability.

where,

m = marks obtained by the candidate.

a = average of marks of all candidates who appeared in the paper mentioned on this scorecard, in the current year.

s = standard deviation of marks of all candidates who appeared in the paper mentioned on this scorecard, in the current year.

K1 and K2 are determined respectively from the mean and standard deviation of marks of all candidates across all papers and years since GATE 2002.

A typical qualitative interpretation of the GATE SCORE, for example, can be as follows:

Percentile Score

The percentile score is not the same as percentage of marks. The percentile score of a candidate shows what percentage of candidates, who appeared in thesame paper in GATE 2005, scored less marks than him/her. It is calculated as follows: Let N be the total number of candidates appearing in that paper and nc bethe number of candidates who have the same all India rank c in the same paper (there can be bunching at a given all India rank). Then all the candidates, whoseall India rank is r, will have the same percentile score P, where

The percentile score in each paper is calculated as follows: Let N be the totalnumber of candidates appearing in that paper, and nc be the number of candidateswho have the same all India rank c in the same paper (there can be bunching ata given all India rank), then all the candidates, whose all India rank is r, will have the same percentile score P, where

P = {(no. of candidates securing marks less than the candidate concerned)/N}x100

The evaluation of the ORS is carried out by a computerized process using scanning machines, with utmost care. Requests for revaluation of the answer script and re-totaling of marks will not be entertained.

The GATE result and particulars of the qualified candidates will be made available to interested organizations (educational institutions, R and D laboratories, industries etc.) in India and abroad based on written request by the organization and on payment. Details can be obtained from GATE Chairmen of IITs / IISc.
