This article will cover the overview of the GATE 2025 normalisation process which will demonstrate why is it done, and how the final score of GATE is calculated using the normalisation process.
GATE 2025 Normalisation Process-
The GATE 2025 exam will be held on February 1, 2, 15, and 16, 2025 in various sessions for 30 papers. Since the GATE exam is held in multiple sessions for various papers, the difficulty level of the exam might vary. One session may have easier questions and the other session may have tough questions. Therefore, the authorities use the GATE 2025 normalisation process to determine a score that is equal to the level of the difficulty level of the exam. The GATE normalisation process is used to provide students with a fair
GATE 2025 result
. The authorities will prepare the GATE result after considering the student's raw marks, score, and normalized score. The GATE 2025 marks are the raw marks scored by the student in that particular exam which is calculated out of 100. Whereas, GATE scores are calculated out of 1000 using a formula. The authorities convert the GATE marks into scores and prepare the results. GATE normalisation process 2025 is used to prepare results for papers with multiple sessions like Computer Science and Engineering and Civil Engineering. In the GATE 2025 result, students who will appear for a paper with a single session will have their GATE scores and students who have appeared for multiple session papers will have normalized scores.

About GATE Normalisation Process 2025
GATE 2025 papers will be conducted in multiple sessions. Different sessions will have different levels of difficulty for the GATE paper. Hence, in order to conduct a fair examination and evaluate a fair cutoff score, the GATE 2025 normalisation process will be done. Often students who have appeared for the exam get confused as to how the normalisation process is done and how is the final score calculated for GATE. This article will demonstrate the formula and process for the GATE normalisation process to help students get an idea about the same.
GATE 2025 Normalisation Process Formulae
The standard deviation and variance formula is used for calculating the normalised score for the students appearing in the multi-session papers of GATE.
The actual formula which is used to calculate the GATE normalisation score is:
Where,
mij : the marks obtained by the student in the session
mgt : the average marks of students for all sessions
mgq : the sum of mean & Standard deviation for all sessions
mti: the average marks of students for one session
miq : the sum of mean & Standard deviation for one session
Let us understand the normalisation process with the help of a case study.
Let us assume there are 5 students who have appeared for the GATE multi-session papers. The marks obtained by all of the 5 students out of full marks are as follows:
student | Marks Obtained |
|---|---|
C1 | 144 |
C2 | 152 |
C3 | 142 |
C4 | 132 |
C5 | 120 |
Now, the average score for the marks obtained by all the students will be calculated using the formula:
C1 + C2 + C3 + C4 + C5 / 5
Which will be: 144 + 152 + 142 + 132 + 120 / 5
= 690/ 5
=183 , which is the average score
Further, the variance of the average score for all the students will be calculated using the formula:
Square of the sum of (Actual score- Average score)/ total students
Which will be: sq. [(144-138) + (152-138) - (142-138) - (138-132) + (138-120)] / 5
Variance will be: sq. 6 + sq. 14 + sq. 4 +sq. 6 + sq. 18 / 5
= 24
Now, the standard deviation for the calculated variance will be derived using the formula: Sq. root (variance)
Which will be: sq. root (24)
= 4.89
= 5 (Nearest sum)
This will be the final normalised score.
After the calculation of the normalised score, the final score is released by the GATE examination authority for all the papers.
How to Calculate GATE Normalised Score 2025?
GATE authorities uses formulas to convert the marks of the student into scores. Since certain exams are given over multiple sessions, a suitable normalisation formula is applied to take into consideration any variations in the question paper difficulty between sessions. The fundamental tenet of the GATE 2025 normalisation process is that "the distribution of students' abilities is the same across all sessions in all multi-session GATE papers." This premise is proven by the enormous number of students who appear in GATE multi-session papers and the random session allocation process.

How to Calculate GATE Score 2025?
GATE score is calculated out of 1000 and GATE marks is calculated out of 100. The GATE Score for single-session papers is calculated using the real GATE marks achieved by the students. For example, if you appeared for a Biotechnology Engineering paper and scored 70 marks out of 100, then 70 marks are your real or raw marks that will be used to calculate GATE scores. The GATE score for papers with multiple sessions like Computer Science and Engineering and Civil Engineering are calculated using actual/ raw marks and Normalized scores.
The following formula is used to calculate GATE scores:
where,
- M: marks recvied in GATE (actual marks for single-session papers and normalized marks for multi-session papers)
- Mq: Qualifying marks for general category student in GATE paper.
- Mt: Mean of marks of top 0.1% or top 10 (whichever is larger) of students who appeared for GATE (in case of multi-session papers including all sessions)
- Sq: 350, is the score assigned to Mq
- St: 900, is the score assigned to Mt
GATE Qualifying Marks 2025
GATE 2025 qualifying marks are the marks that students must score to pass the exam. GATE qualifying marks are released along with the GATE 2025 result on the official website. The GATE exam's qualifying scores (out of 100) varied for each category. Check how GATE qualifying marks 2025 are calculated by referring to the table below.
Category | GATE Qualifying Marks (Out of 100) |
|---|---|
General Category (Gen) | 25 or μ + σ, whichever is higher* |
Other Backward Classes (OBC) | 90% of the general category's qualifying mark |
Scheduled Caste and Scheduled Tribe (SC/ST) | 2/3 (i.e., 66.67%) of the general category's qualifying mark |
NOTE:
In the General Category, μ is the mean and σ is the standard deviation of the marks obtained by all students who appeared in that paper.
