A semester marksheet contains everything you need to verify your own result, and most students never read past the SGPA line. That is a missed opportunity, because marksheets do contain errors, and because the columns you are skipping explain exactly how your number was produced.

The subject rows

Each subject occupies one row, typically with four or five pieces of information:

• Subject code. The reliable identifier. Colleges shorten subject names inconsistently, so when you are matching your marksheet against a syllabus, match on the code.
• Subject name. Often abbreviated to fit the column. Do not read anything into the wording.
• Credit hours. The weight of this subject in your semester average. The most important number on the row, and the one most often overlooked.
• Grade. Your letter grade for the subject.
• Grade point. The numeric value of that letter on your university's scale. Some marksheets show it; some expect you to read it off the legend.

Where a subject has a separate practical or lab component, it usually appears as its own row with its own credits and its own grade. Two rows for one course is normal, not a printing error.

The legend

Somewhere on the sheet — often the reverse side, often in small print — is the grade-to-point legend for your university. This is the authoritative scale for your result, and it overrides anything you read online, including anything on this site.

It is worth actually looking at, because the four Nepali semester-system universities do not share a scale. Pokhara University tops out at a plain A worth 4.0; Tribhuvan, Kathmandu and Purbanchal place A+ at 4.0 and put a plain A at 3.6. If you have ever compared GPAs with a friend at another university and felt the numbers did not make sense, this is why.

The totals

Below the subject rows you will usually find total credit hours for the semester, total grade points earned, and the SGPA. Later marksheets and the final transcript add cumulative figures: total credits completed and CGPA.

These are all checkable. Multiply each subject's grade point by its credits, add them, and divide by total credits — you should reproduce the SGPA to two decimal places.

SGPA = Σ (Grade Point × Credit Hours) ÷ Σ (Credit Hours)

Checking for errors

Marksheet errors are uncommon but not rare, and they are far easier to correct in the weeks after publication than years later when you need the transcript for a job or a visa. Three checks take about five minutes:

• Are all your subjects there? Count the rows against your registration. A missing subject is the most consequential error and the easiest to spot.
• Do the credit hours match your syllabus? Compare the total against your semester's official credit load. A mismatch here means either a missing row or a wrong credit value.
• Does the SGPA reproduce? Run the formula above. If your arithmetic disagrees with the printed figure, recheck your grade points against the legend before contacting anyone — using the wrong scale is a far more likely explanation than a board error.

Why CGPA is not the average of your SGPAs

A frequent source of confusion when reading a final transcript: the CGPA line is usually not the plain average of the SGPA lines above it. CGPA is credit-weighted across semesters, so a heavier semester counts for more.

CGPA = Σ (SGPA × Semester Credits) ÷ Σ (Semester Credits)

If your semesters all carry identical credit loads the two methods agree, which is why the difference goes unnoticed for so long. As soon as one semester is lighter — a project semester, say — they diverge.

Keep your own copy

Marksheets get lost, and exam sections are slow. Entering each semester into the gpaNepal calculator as results arrive gives you a running record you can export to CSV or PDF, and it verifies the official arithmetic as a side effect. If the calculator and the marksheet disagree, one of them is wrong — and either way you want to know before the transcript matters.
