Hi Kunal!

You will just have to shift the vairables to get your percentage. 

Percentage is calculated as: Marks Obtained/ Total Marks x 100

Hence you can put in whatever marks you got from the total and calculate your percentage.

Hope this helps!

Hey Kunal!

So, the best of four percentage you want to calculate depends on the course you are seeking admission to, in that case you will take the required four subjects into calculation.

In this case your best four can be calculated by dividing the obtained marks by the total marks.
