These tools follow the rules Singapore students are graded by: Singapore Polytechnic's grade points for your poly GPA, and the 70-point University Admission Score used from 2026. Every rule links to the page it comes from, with the date GradeCat opened it. Each tool works right away with no account, and your grades stay in your browser.
Tools
Which tool do I need?
- What is my poly GPA or cGPA? Use the Poly GPA Calculator. Enter each module's credit units and grade. With 4 CU at A, 3 at B+, 4 at C and 2 at D-, the GPA is 35.5 ÷ 13 = 2.73 to 2 decimals.
- What is my UAS, or rank points, from my A-Level grades? Use the A-Level UAS Calculator. H2 grades A, B and C with GP at B give 61.25 out of 70, and H1 MTL at A raises it to 62.34.
- How many points is a grade worth? The Poly and A-Level Grading Scale page has the tables: a B+ at SP is 3.5, and an H2 A is 20 UAS points.
- What percentage are my marks? The Grade Calculator adds up marks out of any total: 34 out of 40 is 85%.
How poly GPA and the UAS work
Singapore Polytechnic's Grading System gives each grade a point from 4.0 down to 0, and your GPA is the credit-unit-weighted average of those points, failed modules included. From 2024/2025, SP may leave up to two electives out of your final cGPA, only when that improves it.
The University Admission Score, as Anderson Serangoon Junior College sets it out, adds your best three H2 content subjects and General Paper for a score out of 70. H1 Mother Tongue and a fourth content subject count only if they raise it. We opened each page on 4 November 2026, and each tool page lists its own.

Tools that work with any marks
These GradeCat tools work with marks and percentages, which add up the same way anywhere. Their letter grades follow US scales, so read the percentage.
- Grade Calculator: your percentage from marks, like 34 out of 40.
- Weighted Grade Calculator: one percentage when parts of a module count differently.
- Final Grade Calculator: the score you need in a final exam that counts for a set share.
- Test Grade Calculator: for teachers, the percentage for each score on a test.
Not covered yet
- Nanyang Polytechnic (NYP): its regulations give a non-graded pass 1.0 grade point, a rule that needs another check first.
- Republic, Ngee Ann and Temasek Polytechnics, and ITE: their grading pages have not been checked.
- University GPAs at NUS, NTU, SMU and the others.
- O-Level aggregates for JC and polytechnic admission, such as L1R5 and ELR2B2, and the PSLE Score: MOE's pages do not say how each grade becomes points.
