Does it really matter whether you study from ICSE or CBSE Board?


There is a common notion among students that studying from CBSE board may help them find their way to the top of the merit list. They feel studying from this board increases their chances of scoring highest marks, and ultimately join the league of Top JEE Rankers.

Though hailing from CBSE board enhances your chances of clearing the toughest engineering and pre-medical exams. This does not mean that this board guarantees top rank in JEE Main. It simply means that the CBSE student may only get a head start while preparing for competitive exams, in particular – JEE Main & Advanced.

Importance of Class XII board exam marks

While Class XII board marks do influence JEE Main Rank, the board which you have appeared from barely matters as JEE Main rank is calculated after normalizing results across different Class XII boards.

What is Normalization?

Normalization definition in layman’s term:

Before calculating JEE Main Rank, CBSE normalizes your Class XII scores with respect to results of other boards. While normalizing your score, the difficulty level of your board exam and the overall scoring pattern in different papers are considered. Other than these two, there are various Factors considered in calculating normalized qualifying exam marks.

How is JEE Main rank calculated after normalization?

JEE Main marks scored by a candidate = A
Aggregate marks in Class XII board (basis a list of five subjects meeting the JEE Main 2016 Eligibility Criteria) = B
Convert marks into percentile by formula below:
Total number of students who have scored less that B *100 = Percentile (P)

Total number of students who appeared in that particular board XII exam

JEE Main 2016 aggregate marks corresponding to Percentile (P) at the All-India level = B1
JEE Main 2016 aggregate marks corresponding to Percentile (P) at particular board level = B2

Computation of normalized Class XII board score of the candidate:
Bfinal = 0.5 * (B1 + B2)

Calculation of the composite score for JEE Main 2016 Merit List:
C = 0.6 * A + 0.4 * Bfinal

This composite score forms the basis for the JEE Main 2016 AIRs

Let’s understand how board marks does not play a crucial role in declaring JEE Main Rank. Check below the example:

Rahul from CBSE board scored 97% His percentile in qualifying exam was 99.74% and his normalized marks was calculated as 239 marks.
Samira scored 60% in Class 12th from Rajasthan board. Her percentile in qualifying exam was calculated to 99.86%. Her 12th normalized score calculated is 240.
In the above two examples, we have seen despite of the high and low percentage in Class 12th, both the student’s normalized score and percentile is more or less similar; not much difference. This clearly indicates that getting higher percentage in Class 12th exam does not guarantee best rank in JEE Main. This is the advantage of normalization!

So, if you have earned less percentage in board exam, don’t worry! The normalized marks will fill the gap when the JEE Main rank will be announced.
