• Theory Exams: Most of them have theoretical papers that contribute greatly to the final grade. English, Mathematics, Economics etc., most rely on written exams.

Practical Instances of How to Calculate ISC Percentage 

This section illustrates a practical solution of how to calculate ISC percentage.

Let us assume that a candidate secures 1155 marks out of 1200 marks in the board examination. So, the percentage calculation is as follows:

Number of marks scored = 1155

Maximum marks = 1200

Therefore, percentage of marks = (Marks scored / Maximum marks) *100

                                                    = (1155 /1200) * 100

                                                    = 96.25 %
