Over 4 lakh candidates appeared for the MHTCET 2023 exam. To accommodate all candidates effectively, the State Common Entrance Test Cell of Maharashtra implemented different sessions, each offering a unique set of questions with varying difficulty levels.
But what if the MHTCET paper of your shift was difficult? And your friend’s was easy? How will fairness be ensured?
Through the MHTCET’s Score Normalization Process of course!
Normalization is a process in which the scores secured across different exam shifts are adjusted to a common scale. Thus, every candidate’s performance is evaluated based on similar exam parameters. This ensures that candidates are neither benefited nor at a disadvantage due to the difficulty level of their shift examination.
The end result (i.e. your MHTCET score) of this normalization process is represented in terms of a percentile score.
STEP 1: Distribution of Examinees
In order to distribute the examinees evenly, candidates will be randomly assigned to four sessions over the course of two days, with two shifts per day. The goal here is to ensure that each session has a roughly equal number of candidates.
Session1: Day1 Batch1
Session2: Day1 Batch2
Session3: Day2 Batch1
Session 4: Day2 Batch2
If there are additional days or shifts required, the candidates will be divided accordingly to maintain fairness in the distribution. This approach ensures that there is no bias in the allocation of candidates for the examination. Moreover, considering the large number of examinees across the country, the likelihood of any bias occurring in the distribution becomes highly unlikely.
STEP 2: Preparing Results for Each Session
The results for each session will be prepared in two formats:
A quick look at percentile scores and how to calculate them
Percentile scores are your raw marks transformed into a scale of 100 to 0 for each session, where 100 is the highest score obtained in each session.
Here’s how to calculate the percentile score of a candidate:
100 * (No. of candidates appeared in the session with raw score ≤ candidate's score) ÷ Total number of candidates in the exam
Note: The percentile score should not be confused with the percentage of marks obtained by the candidate. The percentile of the total score will not be an aggregate or average of the percentiles of individual subjects.
In order to better grasp the concept of percentile scoring and the normalization process, let's consider an example.
Suppose a test was conducted in 4 sessions as per the details given below:
(I) Distribution of candidates:
Session1: Day1 Batch1
Session2: Day1 Batch2
Session3: Day2 Batch1
Session 4: Day2 Batch2

According to this scoring method, the highest raw score in each paper will be assigned a percentile of 100. This indicates that 100% of the candidates have scores equal to or lower than the highest scorer or topper in that session.
For each session, the highest raw scores will be assigned a normalized percentile score of 100.

The percentile score will serve as the normalized score for the examination, replacing the raw marks of the candidate. To avoid clustering or ties, the percentile scores will be calculated up to 7 decimal places.
The scores will be calculated separately for each of the three subjects (Mathematics, Physics, Chemistry) and the overall total score as follows:
Total Percentile (T1P) = 100 * (No. of candidates appeared from session with raw score equal to or less than T1 score ÷ Total no. of candidates appeared in the session)
Mathematics Percentile (M1P) = 100 * (No. of candidates appeared from session with raw score equal to or less than M1 score in Mathematics ÷ Total no. of candidates appeared in the session)
Physics Percentile (P1P) = 100 * (No. of candidates appeared from session with raw score equal to or less than P1 score in Physics ÷ Total no. of candidates appeared in the session)
Chemistry Percentile (C1P) = 100 * (No. of candidates appeared from session with raw score equal to or less than C1 score in Chemistry ÷ Total no. of candidates appeared in the session)
STEP 3: Compilation of MHTCET Scores
The total MHTCET scores will be compiled as follows:
The percentile scores for the Total Raw Scores in all four sessions (calculated in Step2), will be combined and referred to as the CET scores. These scores will be utilised for the compilation of the final results.
Separate percentiles will be calculated for the Total Raw Score as well as the Raw Scores in the three subjects (Mathematics, Physics and Chemistry) in all four sessions.

The percentile scores will be calculated in a similar manner for Biology and overall scores in the subjects of Physics, Chemistry and Biology (PCB).
With so many students banking on the MHTCET scores for their chosen academic paths, fairness is the basis of their merit. While this Normalization Process might seem tedious, it is nonetheless essential.
