JEE Main Mark Vs Percentile

**Here is a sample of JEE Main Scorecard:**

**How to Calculate JEE Result/Rank?**

JEE Main result is determined through the process of normalization. As JEE Main is conducted in a few shifts and different days, it is possible for students to get easy questions on some dates and tough questions on another. For this purpose, the normalization process is used to determine percentile and rank.

##### Percentile Score:

The percentile score is based on the performance of all the candidates appearing in the exam. As per the official website of JEE Main, "The Percentile Score indicates the percentage of candidates that have scored EQUAL TO OR BELOW (same or lower raw scores) that particular Percentile in that examination. Therefore the topper (highest score) of each session gets the same Percentile of 100 which is desirable. The marks obtained in between the highest and lowest scores are also converted to appropriate Percentiles."

##### Difference Between Percentage and Percentile:

1. A percentage is a number out of 100

2. A percentile score of a candidate will reflect how many candidates have scored below that candidate in an exam. A Percentile score is a value below which a certain percent of observations fall.

##### Normalization Process:

Normalization is the process of identifying a candidate's actual merit/rank by creating the same level playing field for every student.

##### Formula to calculate JEE Main score:

**Calculation of JEE Main Percentile:**

The JEE Main overall percentile for each candidate is calculated on the basis of the percentile of each subject (Physics, Chemistry, and Mathematics).

The formula is:

##### JEE Main Tie Breaking Solution:

##### In the case of two or more candidates securing the same percentile in JEE Main, the ranking will be determined in the priority of the following steps:

##### For B.Tech:

1. Candidate securing more percentile score in mathematics will be ranked higher

2. Candidate securing more percentile score in physics will be ranked higher

3. Candidate securing more percentile score in chemistry will be ranked higher

4. Candidate older in age will be ranked higher

##### For B.Arch:

1. Candidate securing more score in mathematics will be ranked higher

2. Candidate securing more score in the aptitude test will be ranked higher

3. Candidate securing more score in the drawing test will be ranked higher

4. Candidates having a lesser number of negative responses in the paper will be ranked higher

5. Candidate older in age will be ranked higher

##### For B.Plan:

1. Candidate securing more score in mathematics will be ranked higher

2. Candidate securing more score in the aptitude test will be ranked higher

3. Candidate securing more score in planning based questions will be ranked higher

4. Candidate older in age will be ranked higher
