Students unhappy with their TN 12th 2026 marks have two official options: retotalling — a clerical mark recheck — and revaluation, a full re-examination of your answer script by a senior examiner.
The Directorate of Government Examinations (DGE), Tamil Nadu, offers both processes after HSC results are declared. The right choice depends on what you believe went wrong — a calculation error or an under-marked answer. Understanding the difference saves you time, money, and unnecessary stress during the admission season.
- Retotalling checks if marks are correctly added and all answers are evaluated — it does not re-read your answers.
- Revaluation sends your script to a senior examiner who marks it afresh and independently.
- Both processes are applied for online at dge.tn.gov.in within the notified application window.
- Retotalling results arrive faster and cost less; revaluation offers a higher chance of mark improvement.
- In Tamil Nadu, marks are never reduced through revaluation — DGE always retains the higher of original and revised marks.

What is TN 12th Retotalling?
Retotalling — sometimes called recounting — is a clerical recheck of your answer sheet. DGE examiners verify three things: whether every answer in your script has been evaluated, whether page-level marks are correctly added up, and whether the total is correctly transferred to the mark sheet. The examiner does not re-read or re-mark your answers at any point.
If no calculation error or unevaluated question is found, your marks will remain unchanged. This process is best suited for students who suspect an arithmetic or clerical error rather than under-marking of their answers.
What is TN 12th Revaluation?
Revaluation is a fresh evaluation of your answer script by a senior examiner appointed by DGE. The examiner reads your answers independently and assigns new marks without seeing the original marks. If the revaluation marks are higher than your original marks, the higher value is updated on your mark sheet. If they are lower, your original marks are retained — you cannot lose marks by applying for revaluation in Tamil Nadu.
Revaluation is the right option when you are confident your answers were correct or well-attempted but were awarded fewer marks than deserved.

| Can marks decrease? | No | No — DGE retains the higher of original/revised |
| Expected fee | ~₹300 per subject | ~₹500 per subject |
| Expected result time | 2–3 weeks | 4–6 weeks |
| Best suited for | Suspected calculation or clerical error | Under-marked correct answers |
Eligibility for Revaluation and Retotalling
Any student who appeared for the TN HSC (Class 12) March/April 2026 examination and is dissatisfied with their marks in one or more subjects can apply. Key eligibility points:
- Both regular and private students who appeared for the 2026 exam are eligible.
- You must apply within the notified window — typically 15–30 days after result declaration.
- You can apply for retotalling and revaluation for the same subject simultaneously.
- There is no minimum or maximum mark restriction — you can apply regardless of your score.
- Students appearing under compartment or supplementary exams may have a separate application window; check dge.tn.gov.in for subject-specific notifications.
Which One Should You Apply For?
Use the situation guide below to make your decision:
| Your Situation | Recommended Option |
|---|---|
| Your total seems lower than the marks you recall attempting | Retotalling |
| A question appears unevaluated (zero marks for a full attempt) | Retotalling |
| Your answers are correct but the marks awarded are low | Revaluation |
| You need revised marks urgently for a college admission cutoff | Retotalling (faster result) |
| Limited budget and unsure which error occurred | Retotalling (lower fee; covers the most common error type) |
| You want the maximum chance of mark improvement | Apply for both simultaneously |
If you are just a few marks short of a grade boundary or an admission cutoff, applying for both simultaneously is the safest strategy. Retotalling results arrive sooner and may resolve the issue before revaluation is even complete.
How to Apply: Step-by-Step
DGE Tamil Nadu accepts applications online through its official portal. Follow these steps once the window opens:
- Visit the official DGE website at dge.tn.gov.in.
- Click on the Revaluation / Retotalling link under the HSC Results section.
- Log in using your register number and date of birth.
- Select the process — retotalling, revaluation, or both — and choose the subject(s) you want reviewed.
- Review the fee shown for each subject and confirm your selection.
- Pay the fee online using net banking, UPI, or a debit or credit card.
- Download and save your payment confirmation receipt — you will need it to track your result.
Apply early — the portal typically sees very high traffic in the final 24–48 hours of the application window, which can slow down processing.
Fees and Expected Timeline
The table below shows expected fees and timelines based on 2025 trends. Confirm the exact amounts and dates on dge.tn.gov.in once the official notification is published.

|---|---|---|
| Retotalling | ~₹300 | 2–3 weeks after the application window closes |
| Revaluation | ~₹500 | 4–6 weeks after the application window closes |
The application window typically opens within 7–10 days of the HSC result date and stays open for around 15–20 days. If your marks change after either process, DGE issues a revised mark sheet that you can present for college admissions and other official purposes. Contact your school or the nearest DGE regional office if you need the revised mark sheet urgently for an ongoing admission process.
