How the University of Siena GPA formula works

University of Siena converts every graded course into quality points by multiplying the grade's point value by the course's credit hours. Your semester GPA is the total quality points divided by the total credit hours that count toward the GPA, and the result is rounded to the nearest 2 decimal places. Points run from 0.0 up to 30.0, so a higher average is a better result. The scale has no plus/minus steps, so every grade in a band is worth exactly the same number of points.

What gets left out of the average

P and F carry no point value at University of Siena, so a course marked with one of them drops out of the division entirely — it changes neither the top nor the bottom of the fraction. P still earns credit toward your degree while staying out of the GPA, which is why your credit total can climb in a semester where your GPA barely moves.

How this semester rolls into your CGPA

University of Siena official sources state exam grades range from 18 to 30, credits are awarded for passed exams, and averages are weighted by ECTS. In practice that means your existing CGPA is turned back into quality points by multiplying it by your completed credits, this semester's quality points are added on, and the total is divided by your new credit total. Both the semester and the cumulative figures are rounded to the nearest 2 decimal places. Repeat handling is not published as a rule this calculator can apply automatically, so retaken courses need to be checked against the current catalog.

How University of Siena compares with other Italy universities

University of Siena shares the Italian 18-30 exam grade scale with Bocconi University, Politecnico di Milano, Sapienza University of Rome and 9 others, while Universita Cattolica del Sacro Cuore and University of Trento grade on a different scale.

A GPA only means something alongside the scale it was calculated on, which is why comparing raw numbers between institutions — even neighbouring ones — is unreliable. See the Italy comparison table for every university covered there side by side.

Converting this GPA to a 4.0 scale

University of Siena does not grade on the US 4.0 scale. Its scale runs to 30.0 rather than 4.0, with 14 point values in use and 18 as the lowest passing mark. There is no single correct formula for converting that into a 4.0 GPA, and GPAWorld deliberately does not publish one: every graduate school, employer and credential evaluator applies its own conversion table, and a number invented here could cost you an application. Calculate your GPA on this page using the real University of Siena scale, then let the institution you are applying to convert it with their table.

Worked examples

Each example below is run through the same engine the calculator uses, so the numbers show University of Siena's own rounding.

A typical graded semester

A student sitting at 21.60 after 60 completed credits takes 3 courses worth 3 credits each.

  • Core course3 credits × 30 (30.0 points)
  • Elective3 credits × 29 (29.0 points)
  • Lab or seminar3 credits × 27 (27.0 points)

Semester GPA 28.67 · Updated CGPA 22.52

The semester total is 258 quality points over 9 counted credits. Because the cumulative average now spans 69 credits, one semester moves it only a little — this is why a CGPA gets harder to shift the further into a degree you are.

Adding a course graded P

The same student adds a fourth 3-credit course graded P (Pass / approved activity).

  • Core course3 credits × 30 (30.0 points)
  • Elective3 credits × 29 (29.0 points)
  • Lab or seminar3 credits × 27 (27.0 points)
  • Pass / approved activity course3 credits × P (no grade points)

Semester GPA 28.67 · Updated CGPA 22.52

The semester GPA is unchanged at 28.67. P carries no grade points at University of Siena, so the course is removed from both sides of the division — even though the credit still counts toward the degree. Students often expect a fourth course to move the average and are surprised when it does not.

What this semester does to your CGPA

A student with a 21.60 CGPA after 60 credits takes 4 courses worth 3 credits each (12 credits in total). Here is where that CGPA lands if every course comes back at the same grade — calculated with the University of Siena scale and rounding.

Common mistakes when calculating your University of Siena GPA

These are the places where the University of Siena rules differ from what most students assume, and where a hand calculation usually goes wrong.

  1. Counting P courses in the average

    These earn credit at University of Siena but carry no grade points, so they belong in your credit total and nowhere near the GPA division. Including them is one of the most common reasons a hand-calculated GPA comes out wrong.

  2. Borrowing plus/minus values from another university

    The University of Siena table has no plus or minus steps — every grade in a band is worth the same points. Intermediate values like 3.3 or 3.7 do not exist on this scale.

  3. Averaging the grades instead of weighting them

    A course worth twice the credits moves your GPA twice as much. Adding up your grade points and dividing by the number of courses ignores that weighting and is almost always wrong.

  4. Expecting a 0-credit course to move the number

    University of Siena allows them, but with no credit hours they contribute nothing to either side of the division.

  5. Handling a retake by guesswork

    Repeat handling is not published as a rule this calculator can apply automatically, so retaken courses need to be checked against the current catalog. Check the current catalog before assuming an old grade has left your record.

University of Siena GPA — frequently asked questions

What is a passing grade at University of Siena?

18 (18.0 points) is the weakest grade in the University of Siena table that still earns credit. Anything below it is counted in your GPA but earns no credit toward the degree. Individual programmes can set a higher minimum for courses in your major, so check your programme handbook as well.

What is the best GPA you can get at University of Siena?

30.0 on the Italian 18-30 exam grade scale, which you reach by earning 30 (30.0 points) in every course that counts toward the GPA.

Does University of Siena round GPA up?

The cumulative average is rounded to the nearest 2 decimal places, and the semester average is rounded to the nearest 2 decimal places. That is ordinary rounding, so a result sitting exactly half a step along goes up.

Is this a generic Italy GPA formula?

No. This page is generated from the grading configuration for University of Siena alone — its 14 point values, its standard rounding, and its own rules for pass/fail and repeated courses. Other universities in Italy routinely use different point values or a different scale entirely, so the same grades can produce a different GPA elsewhere.

Do pass/fail courses affect my GPA?

No. P earns credit at University of Siena without carrying grade points, so it is excluded from the GPA division entirely. Your completed-credit total goes up while the average stays where it was.

Which grades are excluded from the University of Siena GPA?

P (Pass / approved activity) and F (Fail / not passed) carry no grade points and are left out of the average. Of those, P still earn credit toward the degree.

What happens to my GPA if I repeat a course?

Repeat handling is not published as a rule this calculator can apply automatically, so retaken courses need to be checked against the current catalog.

How much does one semester change my cumulative GPA?

Your CGPA is weighted by every credit you have already completed, so a single semester moves it less the further along you are. Fifteen credits added to sixty already completed is a fifth of your record; the same fifteen added to a hundred and twenty is an eighth of it. Use the calculator at the top of this page with your real completed-credit total rather than estimating the movement.

What percentage is a 30 at University of Siena?

30 covers 30–30% and is worth 30.0 grade points. The full percentage-to-grade table for all 13 graded bands is published on this page.

Is this calculator official?

No. GPAWorld is an independent tool and is not affiliated with or endorsed by University of Siena. The grading data on this page was taken from University of Siena - European Studies course page, University of Siena - Graduation Sessions, and University of Siena - International Guide and last verified on 2026-07-21; every source is linked on this page so you can check it yourself. Your registrar's record is always the authority.

Notes on this university's data

Judgement calls and caveats recorded when this grading configuration was built from the official sources. They are published so you can see exactly what the calculator assumes.

  • University of Siena has its own official grading information and is not treated as a generic Italy formula.
  • Official sources state exam grades range from 18 to 30, credits are awarded for passed exams, and averages are weighted by ECTS.
  • One official page states final-average rounding to the nearest integer for final degree marks; semester GPA remains standard two-decimal rounding in this app.
  • Retake/repeated-exam handling is manual-review because the official sources used for this config do not provide a complete machine-calculable repeat policy.
  • No logo was added because official reuse rights were not confirmed.
