Hello,

calculating your best 4 marks for DU is very important. The Best 4 concept includes the calculation of the marks secured in the top 4 subjects. Amongst the marks obtained in all the subjects in the 12th standard mark sheet, the best 4 is taken to calculate the average. The marks obtained are added and then divided by 4.

Your best 4 will include,

1. One language(core, functional, elective).
2. Marks of the subject in which admission is to be taken (eg. If history Hons is to be taken, history should be the subject included in Best 4).
3. Stream change leads to deduction of the percentile.
4. Two other List A elective/academic subjects
5. 70% of theory marks and 30% practical marks in all subjects is optimum.

So to answer your question,

It depends. Generally, evs is an optional course. The best four is based upon one language which is mandatory and other should be the main stream subjects which you had opted in your 10+2. For example science : (physics, chemistry, maths, economics). If EVS is one of the five subjects then you can choose that for best four.
