Hey! I am class 12th student myself so here’s what I know about it.
I don’t know much about it in other schools but in my cbse school, there is a choice if you want to opt for 5 subjects(excluding physical education) or 6 subjects (including physical education) .
(In some schools, 6 subjects are compulsory. So I think it also has a advantage to it.)
While I opted for 5 subjects since I didn’t chose physical education while some of my friends did .
But at the end of the year, after final board exams -Only our Five best subjects will be included in our percentage.
So this is what I know.
