Calculating ISC Percentage with Six Subjects: A Comprehensive Guide

For students preparing for the Indian School Certificate (ISC) exams with six subjects, understanding how to calculate your overall percentage is crucial. This guide breaks down the process with clear, step-by-step instructions and examples to help you achieve a thorough understanding.

Step-by-Step Guide to Calculating ISA Percentage with Six Subjects

When you have six subjects in your ISC exams, you need to follow a specific method to calculate your overall percentage. Here is a detailed guide:

Total Marks Calculation

The first step in calculating your overall percentage involves determining the total marks you have obtained across all six subjects. Here’s how to do it:

Identify the marks obtained in each subject: Let's say the marks in each subject are as follows:

Subject 1: 80 Subject 2: 75 Subject 3: 90 Subject 4: 85 Subject 5: 70 Subject 6: 95

Add these marks together:

Total Marks Obtained 80 75 90 85 70 95 495

Maximum Possible Marks

The second step is to determine the maximum possible marks for each subject. If each subject is out of 100, then the calculation for the maximum marks would be:

Calculate the maximum marks for six subjects:

Maximum Marks 6 x 100 600

Percentage Calculation

Once you have the total marks obtained and the maximum marks possible, you can calculate your overall percentage using the following steps:

Apply the formula for percentage:

Percentage left( frac{Total Marks Obtained}{Maximum Marks} right) x 100

Substitute the values:

Percentage left( frac{495}{600} right) x 100 82.5

So, in this example, the percentage of ISC marks would be 82.5%. You can replace the example marks with your actual marks to calculate your percentage.

Alternative Calculation Method for ISC Percentage with Six Subjects

Alternatively, if you are allowed to use the best of four subjects method, here’s how to do it:

FREE Preparation:

Identify the relevant subjects: English is always a compulsory subject in the ISC exams, included in the calculation, and the best four subjects from the remaining over five. To choose the best four, pick the subjects with the highest marks.

Total the marks: Add the marks obtained in English and the four chosen subjects with the highest marks.

Calculate the average: Divide the total marks obtained by 5 (the number of subjects considered).

Convert the average to a percentage: Multiply the average by 100 to convert it to a percentage.

Example:

Let’s say the marks in your ISC exams are as follows:

English: 85 Physics: 78 Chemistry: 90 Biology: 82 Mathematics: 88 Computer Science: 75

English and the four best subjects are:

Physics: 78, Chemistry: 90, Biology: 82, Mathematics: 88.

Total marks:

Total 85 (English) 78 (Physics) 90 (Chemistry) 82 (Biology) 88 (Mathematics) 423

Average:

Average frac{423}{5} 84.6

Percentage:

Percentage 84.6 x 100 84.6

Therefore, your ISC percentage based on this example would be 84.6%.

Important Notes:

English is always included as a mandatory subject in the calculation. The best four subjects are chosen from the remaining five subjects based on the highest marks. Always refer to the official ISC guidelines or consult with your board/school authorities for any changes in the calculation method.

By following these steps, you can accurately calculate your overall ISC percentage, ensuring that you understand how your marks contribute to your final result.
