CBSE 12th Result 2025: Failed in One Subject but Took 6 – Will the 6th Subject Replace It?

With the announcement of CBSE Class 12 Result 2025, numerous students who have chosen six subjects would like to know what if they fail in one of the core subjects. Will the sixth subject rescue their overall performance? The answer lies in the subject replacement policy of CBSE — popularly known as the "Best of Five" rule — and it can certainly favor a student under specific situations.

What is the "Best of Five" Rule in CBSE Class 12?

The "Best of Five" rule in CBSE is a policy by which, if a candidate writes six subjects, the board takes the best five subjects into account when calculating the final result. This proves to be especially helpful when a student fails one of the major academic subjects.

Key Subjects Taken into Account

• English (Core or Elective)
• Second Language (Hindi or any elective language)
• Mathematics
• Physics, Chemistry, Biology, etc.
• Other electives such as Economics, History, etc.
• Other subject (e.g., Physical Education, Computer Science, Psychology)

Can the 6th Subject Take the Place of a Failed Main Subject?

Yes, the 6th subject can take the place of a failed core subject only in the following situations:

You Passed the 6th Subject

If you get a failure in one of the five core subjects but pass the sixth subject, CBSE can think of substituting the failed subject with the marks of the passed 6th subject — but only if the extra subject is a valid elective in the scheme of studies.

For instance, in case you pass Physical Education as a 6th subject and fail Mathematics, your performance may be calculated through Physical Education grades instead of Mathematics — as long as you also satisfy the rest of the passing requirements.

You Failed the 6th Subject

If you have failed both a core subject and the 6th subject, then the replacement rule is not applicable, and you will be graded as "Fail" in your result. You'll then have to appear for a compartment exam in the failed main subject.

How the CBSE 12th Final Result Is Calculated

CBSE computes the result of Class 12 on the basis of the best five out of the six subjects only when all requirements are fulfilled. In this way, one low-performing subject (if it's not a mandatory requirement for your desired stream) will not negatively affect your result.

Example Situation:

Here, the student has failed in Mathematics but passed in Computer Science and Physical Education. If Computer Science or Physical Education is the 6th subject, then the system will substitute the failed subject with the better scoring other subject (92), and the student will be labeled as "Pass" in the result.

What If the 6th Subject Does Not Replace the Failed Subject?

In that scenario, the student will have to attend a compartment exam in the failed subject to achieve a pass mark.

The 6th subject in CBSE Class 12 can prove to be a savior for students who lag behind in one key subject — provided the 6th subject is cleared. This policy offers flexibility to students and a fairer chance of passing their board exams. Yet, it's necessary to understand the rules clearly and not completely bank on the 6th subject as a back-up without proper preparation.

If you have failed one subject but have attempted six, and the other subject is passed — you can still be declared Pass, courtesy of CBSE's considerate replacement policy.
