ULisboa official sources state grades use the national 0-20 scale, credits are awarded with a passing grade of at least 10, and ISEG master regulations calculate the final syllabus grade as an ECTS-weighted arithmetic mean. For semester GPA, each GPA-counted course is converted to quality points by multiplying grade points by credits. The semester GPA is the total quality points divided by total GPA-counted credits, then rounded with standard rounding to 2 decimal places. The updated CGPA combines the student's existing quality points with this semester's quality points, then rounds with standard rounding to 2 decimal places.
Pass/fail and non-GPA grades are handled from the University of Lisbon config: supported pass grades are excluded from GPA points. Repeat-course handling uses this rule: The official sources identify the grading scale and ECTS-weighted final-average calculation, but repeated/retaken course treatment is not complete enough to automate safely.
Suppose a student starts with 3.00 CGPA after 30 completed credits and takes these University of Lisbon courses:
The semester GPA is 13.00 and the updated CGPA is 5.31 using this university's rounding rules.
No. This page uses the grading configuration for University of Lisbon. Another university in Portugal can have different grade points, rounding rules, or pass/fail handling.
The calculator multiplies each GPA-counted grade point by its credits, adds the quality points, divides by GPA-counted credits, and applies standard rounding to 2 decimal places.
Pass/fail grades marked as non-GPA in the University of Lisbon config are excluded from GPA points, although credit may still be earned when the grade allows it.
The official sources identify the grading scale and ECTS-weighted final-average calculation, but repeated/retaken course treatment is not complete enough to automate safely.
