PolyU GPA Calculator: 4.3 Scale for Hong Kong Polytechnic

How GPA Is Calculated at PolyU

The Hong Kong Polytechnic University reports the Grade Point Average on a 4.3 scale that has been in force since the 2020/21 academic year. Every subject on the PolyU academic transcript carries a credit value (most lecture subjects carry 3 credits; lab-paired subjects, capstone projects, and final-year projects can carry 6 credits or more). Each letter grade maps to a fixed grade point on the 4.3 scale, with A+ uniquely topping out at 4.3 rather than 4.0. Multiplying grade points by credits rather than averaging unweighted grades means a B+ in a 6-credit final-year project moves the GPA twice as much as the same B+ in a 3-credit general elective.

Two GPA figures appear on a typical PolyU academic transcript. The first is the semester GPA, computed over only the subjects attempted that semester; this drives Dean's Honours List eligibility and academic probation flagging. The second is the cumulative GPA (CGPA), computed across every subject attempted since matriculation, including failed subjects awaiting retake. The CGPA at graduation is the figure used for the Honours classification printed on the degree certificate and for overseas graduate-school admissions.

How to Calculate Sem GPA PolyU Step by Step

The five steps below mirror what the calculator above does automatically. Use them if you want to verify the registry-issued GPA or if you only have a printed transcript without an electronic copy.

1. List every subject. Write down each subject from the PolyU academic transcript with its credit value, letter grade, and whether it is a core programme subject, a major-required elective, or a free elective.
2. Convert grades to grade points. Use the PolyU 4.3 scale (A+ = 4.3 down to F = 0.0). Subjects graded Pass / Fail and audit subjects (status I or N) are excluded from the GPA entirely; do not enter them.
3. Multiply each row. Compute Grade Points x Credits for every subject. A 3-credit subject with an A scores 12.0 quality points; a 6-credit project with a B+ scores 19.8 quality points.
4. Sum and divide. Add the quality-point column to get total quality points. Add the credit column to get total credits. Divide the first by the second.
5. Round. Round to 2 decimal places to match the figure PolyU prints on the academic transcript and on the degree certificate.

Worked example. A second-year PolyU Computing student has six subjects this semester: Data Structures (3 credits, A = 4.0), Operating Systems (3 credits, A- = 3.7), Database Systems (3 credits, B+ = 3.3), Statistics for Computing (3 credits, B+ = 3.3), Software Engineering (3 credits, A = 4.0), and a General University Requirement elective (3 credits, B = 3.0). Quality points: 3 x 4.0 + 3 x 3.7 + 3 x 3.3 + 3 x 3.3 + 3 x 4.0 + 3 x 3.0 = 12.0 + 11.1 + 9.9 + 9.9 + 12.0 + 9.0 = 63.9. Total credits: 18. Semester GPA = 63.9 / 18 = 3.55. That sem GPA sits in the Second Class Upper Honours band (3.00 to 3.59) and falls 0.05 short of the First Class threshold of 3.60.

PolyU Honours Classification on the 4.3 Scale

PolyU awards five degree classifications for taught undergraduate programmes at graduation. The thresholds are uniform across every PolyU faculty, although the median graduating GPA varies by programme (small-cohort programmes such as Hotel and Tourism Management and the JUPAS-A-band streams cluster well above 3.30, while large general-engineering cohorts cluster around 2.80 to 3.10). The Dean's Honours List is a semester recognition layered on top: a student needs the semester GPA at or above 3.70 and must have no F grades that semester.

The Dean's Honours List notation appears on the PolyU transcript next to the qualifying semester and is recognised by Hong Kong employers and overseas graduate admissions offices as a top-of-cohort signal. Multiple Dean's List semesters strengthen scholarship applications such as the PolyU Postgraduate Scholarship Scheme, the Hong Kong PhD Fellowship, and the various government-backed graduate exchange programmes.

PolyU vs Other Hong Kong Universities

All six UGC-funded Hong Kong universities use the same 4.3 GPA scale with the same letter grades and the same A+ ceiling. The First Class threshold and Honours nomenclature differ slightly. The table below summarises the GPA scale and First Class threshold at each.

Cross-university credit transfer between PolyU and HKU, HKUST, CityU, LingnanU, or EdUHK is arithmetically straightforward because the 4.3 GPA scale is identical. CUHK and HKBU cap their GPA at 4.0 rather than 4.3, so transfers in and out of those two universities need a proportional adjustment. World Education Services and Educational Credential Evaluators treat the PolyU 4.3 GPA on equal footing with the other Hong Kong 4.3-scale universities when issuing US-equivalent assessments for graduate-school applications.

PolyU 4.3 Scale: The 2020/21 Transition

PolyU adopted the 4.3 GPA scale effective from the 2020/21 academic year. Before 2020/21, PolyU used a 4-point cap where both A and A+ scored 4.0 grade points, so the highest achievable GPA was 4.00 rather than 4.30. The scale change brought PolyU into alignment with HKU, HKUST, and CityU, all of which had already adopted the 4.3 ceiling. Most other grade points (A- at 3.7, B at 3.0, and so on) were unchanged.

Students who matriculated in or before 2019/20 may have transcripts that mix old and new grading: early-year subjects under the 4-point system and later subjects under the 4.3 system. The cumulative GPA on the final transcript is computed under the rules in force at graduation; check the academic regulations published in the PolyU Student Handbook for the matriculation cohort to confirm which scale applies to the cumulative figure. Postgraduate research students (MPhil and PhD) follow a separate set of regulations published in the PolyU Research Postgraduate Handbook.

Common Mistakes When Calculating PolyU GPA

The five mistakes below drive most GPA disputes that PolyU students bring to the Academic Registry:

• Treating GPA as an unweighted average. Adding the grade points of every subject and dividing by the subject count ignores credit weighting. A 6-credit capstone subject moves the GPA twice as much as a 3-credit general elective.
• Including Pass / Fail or audit subjects. Subjects graded P (Pass) or F-but-graded-as-pass under the credit transfer route do not enter the GPA. Audit subjects (status I) also do not count. They appear on the transcript but do not influence the GPA figure.
• Forgetting failed-subject credits stay in the denominator. An F counts as 0 grade points, but the credit value still appears in the divisor until the subject is cleared on a retake. This is why a single F drags the cumulative GPA heavily, especially in high-credit capstone subjects.
• Mixing up semester GPA and cumulative GPA. The Dean's Honours List uses the semester GPA only. The Honours classification on the degree uses the cumulative GPA. Reporting one when the application asks for the other is a common error on scholarship and graduate-school forms.
• Using the old 4.0 scale for post-2020/21 subjects. Subjects taken from 2020/21 onwards are graded on the 4.3 scale where A+ scores 4.3 grade points. Plugging those grades into an old 4.0-scale calculator under-counts every A+ grade.

Reading the PolyU GPA on Your Transcript and Applications

The official PolyU academic transcript prints three GPA figures per semester block. The Semester GPA appears on the right-hand summary line for that term. The Year GPA appears under the year-end summary block (only on the end-of-year transcript section). The Cumulative GPA appears as the bottom-line figure spanning every term since matriculation. All three figures are computed on the 4.3 scale from 2020/21 onwards and rounded to two decimal places.

Most external applications (scholarships, graduate schools, internships) ask for one of two PolyU GPA figures: the cumulative GPA at the most recent semester (sometimes called Current CGPA), or the cumulative GPA at graduation. The cumulative GPA at graduation is the figure used for the Honours classification printed on the degree certificate and is the figure that overseas graduate admissions offices and credential evaluators use for the US 4.0 conversion. Some application forms request a percentage equivalent of the PolyU GPA; PolyU's published guidance maps a GPA of 4.30 to roughly 93% and a GPA of 1.00 to roughly 50%, with linear interpolation in between (use the percentage band on each letter grade in the scale table above for a per-subject percentage).

Within the PolyU internal scholarship and exchange systems, the cumulative GPA at the end of the previous semester is normally the figure used. The PolyU Outbound Exchange Programme typically requires a cumulative GPA of 2.70 or above at application time; Hall residence (PolyU Student Halls of Residence) recognises a cumulative GPA above 3.00 as a positive factor in renewal review; the President's Honours List recognises students in the top 1% of the graduating cohort regardless of the exact GPA figure.

How to Raise Your PolyU GPA Across Remaining Semesters

The fastest GPA lift across the remainder of a PolyU programme comes from three levers: securing A or A- in high-credit final-year projects and capstone subjects, retaking failed subjects early so the failed-attempt credits clear from the cumulative denominator, and converting B+ grades into A- or A in any subject weighted at 6 credits or more. Because the final-year project alone typically carries 6 credits, lifting that single grade from B+ to A is equivalent in GPA movement to lifting two 3-credit electives.

Use the calculator above to model the lift: enter completed subjects with their actual grades and credits, then add hypothetical rows for the remaining semesters with the target grades and credits. The live GPA read-out shows whether the target Honours class is arithmetically possible across the credits still to attempt. A student currently at GPA 3.30 with 60 credits completed and 30 credits remaining needs an average GPA of 4.20 across the remaining 30 credits to graduate at exactly 3.60, which is borderline; the realistic target may become Second Class Upper Honours rather than First Class.
