In the CBSE system, students can choose to study either 5 or 6 subjects. The final score for their results is determined by adding up the marks obtained in all the subjects they have chosen.

For instance, if a candidate has opted for 5 subjects such as English, Physics, Chemistry, Biology, and Physical Education, their total score will be calculated out of 500. This includes both the theory and practical marks for all 5 subjects.

On the other hand, if a candidate has chosen 6 subjects like English, Physics, Chemistry, Biology, Computer Science, and Physical Education, their total score will be calculated out of 600. This includes the marks obtained in both theory and practical components of all 6 subjects.

In CBSE, a student can have either 5 or 6 subjects in total. For the purpose of result, the final score is calculated by adding up the marks of all the subjects that a candidate has opted for.
If a candidate has 5 subjects say English, Physics, Chemistry, Biology and Fine Arts.
You total score will be calculated out of 500 including all the theory and practical marks of all 5 subjects as applicable.
Let us take the example-
English : 98/100
Physics : T - 64/70  P - 30/30
Chemistry : T - 65/70   P - 30/30
Biology : T - 68/ 70   P - 30/30
Fine Arts : T - 40/40  P - 60/60

So your total percentage will be : 98 + 94 + 95 + 98 + 100 / 500 * 100 = 97%

Simillarly if you have opted for 6 subjects, then total percentage will be calculated out of 600.

Hope this helps
Thanks!!
