GATE Score Card:
a. Score card will be sent only to the qualified candidates. No information will be sent to candidates who are not qualified.
b. The GATE score card is a valuable document. Care should be taken to preserve it. Additional Score Cards, (upto a maximum of two) will be issued on payment basis only once.
c. The Score Card cannot be treated as a proof of category.
d. The score card of the Qualified Candidates will include GATE Score, Percentile Score and Rank.

i. GATE Score
The GATE SCORE of a candidate is a statistical performance index in the range 0 to 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 different disciplines and/or years can be considered to be of equal ability.
GATE Score = K1 + K2 ((m-a)/s)
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:
Ability Level GATE Score Range
Outstanding 800 to 1000
Excellent 675 to 800
Very good 550 to 675
Good 425 to 550
Above average 300 to 425
Average 100 to 300
Below average Below 100

ii. 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 the same 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 n be the 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, 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} x 100]

e. 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.
f. 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.
