how to calculate 12 percentage for RBI grade b ? do i need to calculate all subjects (6) percentage or top 5 ?
See if your board provides you the marks based on the Best 5 subjects then you can use it. But if you board provides the marksheet with a grading based on all the subjects then you will have no options but have to calculate the percentage for 6 subjects.
I hope this answer helps. All the very best for your future endeavors!
