If you’re a Singaporean student planning to apply to U.S. universities, understanding how to convert your academic achievements into the U.S. 4.0 GPA scale is essential. Singapore has a unique and rigorous grading system that varies across educational levels and institutions. Let’s walk through the details so you can make a smooth transition.
Singapore’s Grading System
Singapore’s education system is known for its high academic standards and structured evaluation methods. The grading system differs depending on whether you’re in primary, secondary, junior college (JC), or university. Here’s an overview of the typical grading scales used across different educational levels in Singapore:

| D | 35–49% | Below Average | ||
| E | 20–34% | Weak | ||
| F | Below 20% | Fail | ||
| GCE O-Level | A1 | 75–100% | Excellent | |
| A2 | 70–74% | Very Good | ||

| E | 40–44% | Satisfactory | ||
| S | 35–39% | Sub-pass | Not considered a full pass | |
| U | Below 35% | Fail | ||
| University | A+ | 90–100% | Excellent | Some universities use A+ as 4.3 GPA |
| A | 85–89% | Very Good | ||
| A- | 80–84% | Good | ||
| B+ | 75–79% | Above Average | ||
| B | 70–74% | Average | ||

- The GCE O-Level and GCE A-Level grading systems are based on the British education model and are used for secondary and pre-university education.
- Universities in Singapore generally use a letter grade system, but GPA scales vary by institution (e.g., National University of Singapore [NUS] uses a 5.0 GPA scale).
- Some institutions apply a bell curve grading policy, making it more competitive.
The US 4.0 GPA System
U.S. universities use the 4.0 GPA system to measure academic performance. This system assigns a numeric value to letter grades:
| Letter Grade | GPA Value | Percentage Range (Typical) |
|---|---|---|
| A | 4.0 | 90–100% |
| B | 3.0 | 80–89% |
| C | 2.0 | 70–79% |
| D | 1.0 | 60–69% |
| F | 0.0 | Below 60% |
- An A reflects excellent performance, while a D is the minimum passing grade.
- U.S. universities often distinguish between weighted and unweighted GPAs. Weighted GPAs give extra points for honors, AP, or IB courses (e.g., A in an AP course might be worth 5.0 instead of 4.0). However, unweighted GPAs, which max out at 4.0, are more commonly used for international conversions.
The Conversion Process
Follow these steps to convert your Singaporean grades to the U.S. 4.0 GPA system:
1. Gather Your Grades:
Obtain your transcript or exam report and identify whether the grading is based on percentage, letter grades, or GPA.
2. Match to U.S. Equivalents:
Use the table below to translate your Singaporean grades into U.S. GPA equivalents:
| Singapore Grade | Percentage Range | U.S. Letter Grade | U.S. GPA Value |
|---|---|---|---|
| A+ | 90–100% | A | 4.0 |
| A | 85–89% | A | 4.0 |
| A- | 80–84% | B | 3.0 |
| B+ | 75–79% | B | 3.0 |
| B | 70–74% | C | 2.0 |
| B- | 65–69% | C | 2.0 |
| C+ | 60–64% | D | 1.0 |
| C | 55–59% | D | 1.0 |
| D | 50–54% | F | 0.0 |
| F | Below 50% | F | 0.0 |
3. Assign GPA Values:
For each course, assign the U.S. GPA value based on your Singaporean grade.
4. Calculate Your Average:
Sum the GPA values and divide by the total number of courses.
- If your transcript includes credits, calculate the weighted average by multiplying the GPA value by the credit hours, summing the totals, and dividing by the total credits.
Example:
- A+ (90%) = 4.0
- A (85%) = 4.0
- B+ (75%) = 3.0
- C (55%) = 1.0
Total GPA points = 4.0 + 4.0 + 3.0 + 1.0 = 12.0
Number of courses = 4
GPA = 12.0 ÷ 4 = 3.0

Common Questions Answered
Q: How accurate is this conversion table?
A: This table reflects common grading standards, but some universities may adjust conversions. Contact your target school for specific details.
Q: What if my school uses a different scale (e.g., 5.0 GPA)?
A: Convert it proportionally to the 4.0 scale using the same percentage ranges.
Q: What if I took IB or AP courses in Singapore?
A: Many U.S. universities give extra weight to IB and AP courses. An A in an IB class might count as 5.0 instead of 4.0.
Q: Do O-Level or A-Level grades affect my GPA?
A: No, but they are important for admissions and may be evaluated separately during application review.
Final Tips
- Focus on consistency across your courses. Strong and balanced performance matters more than a single standout grade.
- Clarify grading policies with your institution’s registrar if you encounter inconsistencies.
- Use a GPA calculator to double-check your conversion and simulate different outcomes.
