The Basic Formula

The core formula for calculating the percentage of marks is:

Percentage = (Marks Obtained / Total Possible Marks) x 100

When dealing with marks out of 100, the total possible marks is, of course, 100. This simplifies the calculation significantly.

Step-by-Step Calculation

  1. Identify Your Marks Obtained: Determine the total marks you received.
  2. Apply the Formula: Divide your marks obtained by 100.
  3. Multiply by 100: Multiply the result by 100. In this case, multiplying by 100 after dividing by 100 simply returns the marks obtained.

Example Calculation

Let's say you scored 85 marks out of 100. Applying the formula:

Percentage = (85 / 100) x 100 = 85%

Therefore, your percentage is 85%.

Handling Multiple Subjects

If you have marks from several subjects, you'll need to calculate the overall percentage. Here's how:

  1. Sum Your Marks: Add up the marks you obtained in all subjects.
  2. Sum Total Possible Marks: Add up the total possible marks for all subjects (if each subject is graded out of 100, and there are 5 subjects, this number will be 500).
  3. Apply the Formula: Divide the total marks obtained by the total possible marks, and then multiply by 100.

For example, imagine you have three test scores of 75, 90 and 88 respectively, all scored out of 100 points each. First you sum your scores to receive 253. Then you would divide this by 300 (the total amount of possible points) before multiplying by 100 which should give 84.33%

Why Percentages Matter

Understanding percentages is crucial for several reasons:

  • Academic Assessment: Evaluating your performance in exams and courses.
  • Tracking Progress: Monitoring your improvement over time.
  • Scholarship Applications: Many scholarships require a certain minimum percentage.
