NEB Class 12 Grade Increment (Supplementary) Exam: How-To Guide
If you got NG (Not Graded) or were absent in one or two subjects in your NEB Class 12 exam, the Grade Increment (Supplementary/Chance) exam is your second chance to clear them the same year. You must have D or above in all your other theory subjects, apply through your own school or college (never directly to NEB), pay the form fee, and use your existing registration number. This guide explains eligibility, fees, the timeline after results, and exactly what the exam can and cannot do.

What the Grade Increment (Supplementary/Chance) exam is
The Grade Increment Examination, also widely called the Supplementary Exam or Chance Exam, is a same-year re-examination run by Nepal's National Examinations Board (NEB) for Class 12 (and Class 11) students who fell just short in a small number of subjects. It is administered by the Office of the Controller of Examinations (Grade 11 and 12) in Sanothimi, Bhaktapur. The purpose is narrow and remedial: to give students who received NG (Not Graded) or who were absent in a couple of subjects one more attempt in the same result cycle, instead of waiting a whole year for the next annual exam.
Under NEB's letter-grading system, NG stands for Not Graded and is recorded when a student scores below the minimum pass threshold, generally below 35 percent in the external theory component (or falls short in the required internal or practical portion). D, the lowest passing grade, covers the 35-39 percent band and carries a grade point of 1.6; anything below that is NG with a grade point of 0.0. Because a single NG can drag down or block a student's overall result, the supplementary exam exists to let candidates convert those NG subjects into a pass.
It is important to understand this exam by what it is not. It is not a general grade-improvement scheme for students who already passed but want a higher letter grade. If you passed a subject with a C or a D, you cannot sit this exam simply to push it up. The Grade Increment (Supplementary) exam only targets subjects where you did not clear the bar at all, i.e. NG or absent.
Who is eligible: the D-or-above rule
Eligibility hinges on a single core rule: you must have secured a minimum grade of D (or above) in all your other theory subjects, and have NG or been absent in at most two subjects. In other words, the exam is reserved for students who are otherwise passing and are held back only by a very limited number of ungraded subjects. Students with NG in three or more subjects do not qualify and must instead re-sit the full annual examination in the next cycle.
NEB's published notices spell out the qualifying combinations in near-identical wording each year. A candidate is eligible if they obtained D or above in other theory subjects and: (a) received NG in up to two subjects; (b) were absent in up to two subjects; or (c) received NG in one subject or were absent in one subject. All three scenarios share the same ceiling of two problem subjects and the same floor of D-or-above everywhere else.
Only regular examinees from that year's annual Class 12 exam are covered by the standard notice, which is one reason NEB ties eligibility to the registration-number series for that batch. Practical-only shortfalls, internal-assessment issues, and unusual cases are handled per the notice's specific terms, so always read the current year's official notice rather than assuming last year's rules carry over unchanged.
- D or above in all other theory subjects, AND NG in up to two subjects.
- D or above in all other theory subjects, AND absent in up to two subjects.
- D or above in all other theory subjects, AND NG in one subject or absent in one subject.
- Not eligible: NG/absent in three or more subjects (must re-sit the full annual exam next year).
- Not eligible: wanting to raise an already-passing grade (a C or D you already earned).
What the exam can and cannot do
The single most common misconception is that 'grade increment' means you can boost any grade you like. It does not. The exam can clear an NG so that a failing or blocked result becomes a pass, and it can cover a subject you missed due to absence. That is the entire scope. Success here typically lifts a stuck overall result into a completed, passing grade sheet, allowing the student to move on to higher studies without losing a year.
The exam cannot be used to convert a C into a B, a D into a C, or to chase a higher GPA on subjects you already passed. If a subject is already graded D or above, it is simply outside the eligibility of this exam. This is why relying on the term 'increment' can mislead students; functionally it behaves as a supplementary or make-up exam for NG and absent subjects only.
A practical consequence is that some students who barely passed with several D grades may be disappointed to learn they cannot improve their marks through this route. For genuine grade improvement, students must look at other pathways defined by NEB and their institutions, which are separate from the same-year supplementary process described here.
Fees: form fee and late fee
There are two cost components to plan for: the application (form) fee and, if you miss the first deadline, a higher late fee. The amounts are set by NEB in each year's notice and have changed over time, so treat the figures below as indicative of recent cycles rather than fixed forever. In one recent cycle the application fee was set at NPR 800 per student, with a late fee of NPR 1,600 per student for applications submitted during the grace window. In an earlier cycle the equivalent amounts were NPR 600 (normal) and NPR 1,200 (late).
Older notices used a per-subject fee model in some cases (for example around NPR 1,000 per subject for certain partial/grade-increment categories), which is different from the flat per-student model seen in recent Class 12 supplementary notices. Because of this variation, do not assume the fee structure; read the current notice to confirm whether the fee is per student or per subject and what the exact rupee amounts are.
Payment is made by depositing into NEB's designated bank account, and proof of payment (a bank voucher or evidence of the online transaction) must be attached to the application form. Keep a copy of the voucher and any transaction reference, because your school forwards this documentation to NEB along with your form.
- Application (form) fee: recent cycles around NPR 800 per student (earlier cycles NPR 600).
- Late fee: recent cycles around NPR 1,600 per student (earlier cycles NPR 1,200).
- Some categories/years use a per-subject fee (e.g. around NPR 1,000/subject) instead of a flat per-student fee.
- Attach the bank voucher or online-payment proof to your form; keep your own copy.
How to apply: route through your college, not NEB
A rule that trips up many candidates is that you do not apply directly to NEB. The application is routed through your own school or college, the same institution from which you appeared for the annual exam. You fill the form, pay the fee, and submit everything to your college; the college then compiles and forwards applications, with payment proof, to the concerned NEB office within NEB's deadline. Walking into NEB or attempting a purely individual submission is not how the process is designed to work.
This routing exists because the college verifies your eligibility against your own result (that you have D-or-above elsewhere and NG/absent in no more than two subjects) and confirms your registration details before forwarding. Practically, that means your first stop after a disappointing result should be your college's examination/administration desk, not the NEB portal, so you can pick up the form, confirm you qualify, and learn the college's own internal cut-off, which is usually a day or two ahead of NEB's final date.
Because the process is form-and-voucher based and time-boxed, missing your college's internal deadline can cost you the chance entirely, even if NEB's official window is technically still open. Confirm the exact submission steps, required documents, and internal deadline with your institution as soon as results are out.
- Collect the grade-increment/supplementary form from your college and confirm you meet the D-or-above and two-subject rule.
- Pay the fee into NEB's designated account and get the bank voucher or online-payment proof.
- Submit the completed form plus payment proof to your college (not directly to NEB).
- Your college forwards the applications to the concerned NEB office by the official deadline.
The registration-number rule
Your NEB registration number is central to this exam. You do not get a new registration number for the supplementary exam; you use the same registration number issued for your Class 12 studies and annual examination. NEB's notices restrict eligibility to specific registration-number series so that only students from the relevant batch (the regular examinees of that year's annual exam) can apply through the standard supplementary route.
In practice, notices state that only registration numbers within a defined range or starting with the batch's prefix are eligible. For example, recent notices tie eligibility to registration numbers beginning with the year prefix of that batch (such as numbers starting with '81' or '82' for the corresponding annual-exam cohorts), while older notices used numeric ranges (for instance, registration numbers from a stated lower bound up to a stated upper bound). The exact prefix or range changes every year, so match your number against the current notice.
Keep your admit card, registration number and symbol number handy when filling the form, and enter them exactly as they appear on your Class 12 records. An error in the registration number can delay or invalidate your application, and since your college verifies these details, cross-check them before submission.
Timeline relative to results
The supplementary exam is deliberately scheduled soon after the annual Class 12 results so that eligible students lose as little time as possible. Typically, once NEB publishes the annual results, the grade-increment notice with the application window and exam routine follows within days to a few weeks, and the exam itself is usually held within roughly the same block of a few weeks after results. In a recent cycle, for instance, annual results were published and the supplementary exam was scheduled approximately two weeks later.
Exam sessions are commonly held over two consecutive days, with the sitting time reported in recent notices as 11:00 AM to 2:00 PM. Because the window between results and the application deadline is short, procrastination is the main risk: students who wait to 'decide later' often miss the college's internal cut-off. Treat results day as the start of a countdown.
Specific dates, both Bikram Sambat (BS) and Anno Domini (AD), differ every year and are announced only in each cycle's official notice and routine. Rather than memorising last year's dates, watch the NEB website and your college notice board immediately after results, and act within the first few days. After the exam, the supplementary results are published separately and can be checked via NEB's websites and the usual SMS/IVR channels.
NEB Class 12 Grade Increment (Supplementary) Exam: How-To Guide — FAQ
I failed one subject in Class 12 (got NG). What should I do?+
If you scored D or above in all your other theory subjects and have NG (or were absent) in only that one subject, you are eligible for the Grade Increment (Supplementary/Chance) exam the same year. Go to your college's exam office as soon as results are out, collect the form, pay the fee, and submit through the college before its internal deadline. Clearing that subject converts your blocked result into a pass without losing a year.
Can the grade increment exam boost a subject I already passed?+
No. Despite the name, it cannot raise a grade you already earned, such as turning a C into a B or a D into a C. It only lets you clear subjects marked NG (Not Graded) or ones you were absent for, provided you have D or above in your other theory subjects. Any subject already graded D or higher is outside its eligibility.
How much is the grade increment form fee, and is there a late fee?+
Fees are set in each year's NEB notice and have changed over time. In recent cycles the application fee was around NPR 800 per student with a late fee of about NPR 1,600 per student; earlier cycles used NPR 600 and NPR 1,200. Some categories/years use a per-subject fee instead. Always confirm the exact amount and whether it is per student or per subject in the current notice, and attach your payment voucher to the form.
Do I apply for the NEB supplementary exam directly to NEB?+
No. You apply through the school or college where you studied Class 12, which verifies your eligibility and forwards your form and payment proof to the concerned NEB office. Do not attempt to submit directly to NEB. Check your college's own internal deadline, as it is usually a day or two before NEB's official cut-off.
Do I get a new registration number for the chance exam?+
No. You use the same NEB registration number issued for your Class 12 studies and annual exam. Eligibility is restricted to the registration-number series of the relevant batch, so match your number to the current notice. Enter your registration and symbol numbers exactly as on your records to avoid your application being delayed or rejected.
When is the grade increment exam held after results?+
It is scheduled soon after the annual Class 12 results, typically within about a few weeks, so eligible students do not lose a year. Recent notices set the sitting time at 11:00 AM to 2:00 PM over two consecutive exam days. Exact BS/AD dates change every cycle and appear only in that year's official notice and routine, so act within the first days after results.
