GATE exam score is used to get admission in M.Tech programmes and other master degrees in engineering offered by IITs and IISc of the country. Here is the formula to calculate GATE score:

The GATE percentile is calculated as follows:

P = ( (N- your rank)/ N) x 100

Where P is percentile and N is total number of candidates appeared for exam.

(N- Your rank) indicates the number of candidates who have scored less marks than you.

For example, if total number of candidates are 100 and 90 of them have less marks than you P = (09/100)X100 = 0.9×100 = 90 percentile.

For another example: A guy form Mechanical Engineering have All India Rank (AIR) 99 and total number of student of students appeared for GATE in Mechanical Engineering are 59338 in 2010. Then his percentile would be calculated as

P = ((59338-99)/ 59338) X 100

= (59239/59338) X 100

= (0.9983) X 100

= 99.83

The candidate has 99.83 percentile.

Candidates appear in GATE exam to get admission in IITs and IISc of the country. But here comes the big question how much percentile is enough to get admission. This is really competitive exam and even 99+ percentile will make you confuse about the admission. IITs take their own written test and interview to enrol students.

There are nearly 50-60 seats in every IITs in each department. And considering only old IITs take admission for M.Tech, there will be 7X50= 350 seats for M.Tech in IITs for almost every department.
