Hi

The candidate should be within the Category Wise Top 20 Percentile in their respective 12th standard (or equivalent) Board Examination.

The marks secured in the following five subjects will be considered for calculating the aggregate marks and the eligibility for fulfilling the top 20 percentile criterion -

1.Physics

2.Chemistry

3.Mathematics

4.A language (if the candidate has taken more than one language, then the language with the higher marks will be considered)

5.Any subject other than the above four (the subject with the highest marks will be considered)

In your case, apart from PCM you must have had English, that would be considered( as the 4th subject ). And best out of Computer Science and Environmental Sciences, i.e. marks scored in Environmental Sciences will be considered.

Hope this helps.
