Revaluation Meaning
Revaluation is the process of rechecking or reassessing an answer script when a student believes the marks awarded are not accurate. It provides a second evaluation opportunity without rewriting the exam.
Revaluation generally includes:
- Re-totaling of marks
- Verification of unanswered questions
- Rechecking evaluation accuracy
- Ensuring no answer was left unassessed
This process helps maintain transparency and fairness in academic evaluation.
When to Apply
Students should consider applying for revaluation if:
- Marks are significantly lower than expected.
- There is a large difference between internal and external marks.
- A student narrowly failed a subject.
- There is suspicion of totaling or marking errors.
Revaluation applications are usually accepted within a limited period (often 7–15 days) after the result announcement.
Revaluation Procedure
The standard process for revaluation includes:
- Result Review: Carefully check subject-wise marks.
- Application Form: Obtain or download the revaluation form from the college or technical board portal.
- Fee Payment: Pay the required revaluation fee per subject.
- Submission: Submit the application before the deadline.
- Waiting Period: Allow time for rechecking and result publication.
After revaluation, the revised marks (if changed) are updated in official records.
Revaluation Outcomes
Revaluation may result in:
- Increase in Marks: The student benefits from the corrected evaluation.
- No Change: Marks remain the same.
- Decrease in Marks: In some systems, marks may reduce if errors are found.
Students must be aware that the revaluation result is usually considered final.
Supplementary Exam Meaning
A supplementary exam (also called a compartment or backlog exam) allows students to reappear for subjects they failed or missed during regular semester exams.
Supplementary exams help students:
- Avoid losing a full academic year.
- Clear backlogs.
- Continue progression to the next semester (subject to rules).
It is a second opportunity to pass the subject through a fresh examination.
Eligibility Criteria
Students are generally eligible for supplementary exams if:
- They scored below the minimum passing marks.
- They were absent due to valid reasons.
- They failed in one or more theory/practical subjects.
- They meet attendance requirements.
Some boards allow progression with limited backlogs, while others require clearance before promotion.
Supplementary Exam Process
The supplementary exam procedure typically includes:
- Notification Release: The technical board releases the supplementary exam schedule.
- Application Submission: Students apply through the college exam section.
- Fee Payment: Exam fee must be paid per subject.
- Admit Card Issue: The hall ticket is issued before the exam.
- Examination: Student appears for the theory/practical exam again.
- Result Declaration: Fresh marks are awarded.
Supplementary exams are usually conducted within a few months after regular results.
Passing Requirements
To clear a supplementary exam:
- Students must score the minimum required passing marks.
- Internal assessment marks may remain the same (in most cases).
- Only external exam marks are updated after reappearance.
Once passed, the subject is cleared and recorded in the marksheet.
