“Best of five” is a phrase every board student hears, but many students are not sure exactly what it means, or whether it applies to them. This guide explains how to calculate best of 5 percentage, who can use it, and what it means for your result. In simple terms, it means your percentage is calculated from your five best subjects, rather than from every subject you took. That can raise your percentage by one or two points — sometimes enough to cross a cut-off.
What Does Best of Five Mean?
If you took six subjects, the best-of-five method drops your lowest score and calculates the percentage from the remaining five. If you took five subjects, there is nothing to drop, and your percentage is simply your total out of the maximum for those five subjects.
The idea behind the rule is fairness. A student who took an extra subject should not be punished for a lower mark in that subject, especially when the extra subject was optional. Boards and colleges that accept best of five recognise that the five strongest subjects give a fairer picture of a student’s ability.
Which Boards Use Best of Five?
The Maharashtra State Board is the best-known example: for Class 10 (SSC), the percentage is calculated on the best five subjects out of six. Several other state boards use a similar rule, although the details differ. CBSE does not officially publish a single best-of-five rule, but many schools and colleges calculate CBSE Class 10 and Class 12 percentages on the best five subjects when a sixth subject is present.
ICSE follows a similar practice for many purposes: the percentage is often calculated on the best five subjects, with English compulsory. For ISC Class 12, the common practice for university cut-offs is best of four, including English. Because the rule changes by board and by college, always check the instructions on the form you are filling in.
The Formula
Best of five percentage = (Total of your five highest subject marks ÷ Total maximum marks of those five subjects) × 100
If each subject is out of 100, the maximum is 500. If subjects have different maximum marks, for example a subject out of 80 and another out of 100, add the maximum marks of the five subjects you are counting, not a round 500.
Worked Example
Take a Class 10 student with these marks out of 100: English 79, Marathi 84, Mathematics 91, Science 86, Social Science 74 and Information Technology 96.
To calculate best of 5 percentage, first arrange the marks from highest to lowest: 96, 91, 86, 84, 79, 74. Drop the lowest, 74 in Social Science. Add the remaining five: 96 + 91 + 86 + 84 + 79 = 436. Divide by 500 and multiply by 100 to get 87.2%. If all six subjects were counted, the total would be 510 out of 600, or 85%. The best-of-five method gives a higher, and in this case more representative, result.
When English Must Be Included
Some boards and colleges make English compulsory in the best-five set, even if it is not one of your five highest marks. In that case, take English plus your four highest other subjects. Using the example above, if English must be included, the set is English 79, Information Technology 96, Mathematics 91, Science 86 and Marathi 84, giving 436 again — but in other cases, forcing English in can lower the total. Read the rule before you choose your five subjects.
Common Mistakes
The most common mistake is dropping a compulsory subject. If your board counts a language or a practical subject as compulsory, you cannot drop it, however low the mark. Another mistake is dropping the wrong subject — always sort your marks before you choose. A third mistake is using the wrong maximum: if one subject is out of 80, the total maximum is not 500. Finally, do not assume that every college accepts best of five. Some colleges, especially for professional courses, ask for the aggregate of all subjects, or for specific subjects such as Physics, Chemistry and Mathematics.
Best of Five and Stream Choice
For Class 11 stream selection, schools often look at subject-wise marks rather than the overall best-of-five percentage. A student with 88% overall but only 62 in Mathematics may still struggle to get Science with Mathematics. So use your best-of-five percentage for forms and cut-offs, but use your subject marks when you choose a stream.
Keep both figures ready: your best-of-five percentage and your overall percentage. Note the method beside each one. When a form asks for a percentage, give the figure that matches its instructions — and if it does not say, use the overall percentage, because that is the figure your marksheet supports most directly.
