For all papers for which there is only one session, actual marks obtained by the candidates will be used for calculating the GATE Score. For papers in multi-sessions, normalized marks will be calculated corresponding to the raw marks obtained by a candidate and the GATE Score will be calculated based on the normalized marks.
The GATE score will be computed using the formula given below.

In the above formulae
M: marks obtained by the candidate (actual marks for single session papers and normalized marks for multi-session papers),

Mq: is the qualifying marks for general category candidate in the paper,
¯M_t: is the mean of marks of top 0.1% or top 10 (whichever is larger) of the candidates who appeared in the paper (in case of multi-session papers including all sessions),
S_q 350, is the score assigned to Mq,
S_t: 900, is the score assigned to ¯M_t
In the GATE the qualifying marks (Mq) for general category student in each subject will be 25 marks (out of 100) or μ + σ, whichever is larger. Here μ is the mean and σ is the standard deviation of marks of all the candidates who appeared in the paper.
