Hi, in order to calculate your best of four percentage for B.Com/B.Com Honors, Two subjects english and maths are neccessary to include. The next two subjects can be the ones on which you have scored better.

So according to this the add up will be 79(english) + 33(maths) + 95(economics) + 83(business studies) = 290 marks

Your best of four percentage becomes 72.5%

Based on this percentage you'll get admission in DU Colleges.

Good Luck
