### How is JEE Main Rank Calculated?

JEE Main rank is calculated by combining two different scores. The first score is your JEE Main score, and another score is normalized class 12 marks. Normalized Class 12 marks are nothing but the average of the two JEE Main score, one is decided by considering All boards across India and another is calculated by just considering only your board. So, JEE Main Rank Merit list is made by combining these two scores. And then these scores are arranged accordingly based on merit and your rank is then calculated.

**For calculating the JEE Main Rank we need the following two numbers:**

1. Your JEE Main Marks – Which we will assume is 80.

2. Normalized Class 12 marks.

Now this normalized Class 12 marks is nothing but the average of two different JEE Main score (B1 and B2). These are only two numbers which make the scoring process complicated. But we will explain it step by step.

**Step 1 for calculating JEE Main Rank – **

The first step is to calculate your Class 12 percentile. What is percentile? (Number of students scored lesser than you)*100 / Number of students eligible for JEE Main.

Now, we will assume you score 75 percent. The number of students scores lesser than you are 9000, and a number of students eligible for JEE Main is 15000.

**So your percentile is = (9000*100)/15000 = 900/15 = 60 Percentile**

**Step 2 for calculating JEE Main Rank –**

Step 2 is to calculate B1. While calculating the B1, we consider all the students appearing for JEE Main across India.

Here is the formula to calculate B1:

For every score, there is some number of students scoring lesser than that score. For example, For JEE Main score 53, 929326 students scored less than 53.

Now we will assume that the number of students appearing for JEE Main across India is 1548726.

Now we will Divide 929326 by 1548726 and multiply it by 100. We will get = 100 x (929326/1548726) = 60.00 percentile.

In this way, we assign a score (53) to every percentile (60.00) and that score is B1.

**So, here B1 is 53.**

**Step 3 for calculating JEE Main Rank –**

Now we have to figure out B2.

We calculate the B2 in the same way as we calculate B1, but here we only consider the students from your board.

So, suppose students appearing from your board is 100000. And the number of students scored lesser than 42 is 60000.

So, we will now divide 60000 by 100000 and multiply by 100. We will get = 100 x (60000/100000) = 60.00 percentile.

**So, here B2 is 42.**

Now we will get that normalised Class 12 marks:

(B1+B2)/2 = (53+42)/2 = 47.5

Now we will put all these data into the below formula:

[(JEE Main Marks)*60 + (Normalised Score of Class 12)*40] / 100

Here we will assume your JEE Main Score is 80.

**[(80*60) + (47.5*40)] / 100 = 67.**

Now that we have got your JEE Main final score, it will be arranged in the merit order and then your rank will be determined accordingly.
