What is Quarter GPA?
Quarter GPA is your Grade Point Average calculated for a single academic quarter (approximately 10-11 weeks). Universities on the quarter system divide the academic year into three main terms—Fall, Winter, and Spring—plus an optional Summer quarter. This system is used by many prestigious institutions including the University of California system, Stanford, Dartmouth, and Northwestern.
📖 Quarter System vs. Semester System
| Aspect | Quarter System | Semester System |
|---|---|---|
| Terms per Year | 3 (+ Summer) | 2 (+ Summer) |
| Term Length | 10-11 weeks | 15-16 weeks |
| Typical Course Load | 3-4 courses/quarter | 4-5 courses/semester |
| Units per Course | 4-5 quarter units | 3-4 semester credits |
| Full-Time Load | 12-15 units | 12-15 credits |
| Annual Units | ~45 quarter units | ~30 semester credits |
Grade Point Values
| Letter Grade | Percentage | GPA Points |
|---|---|---|
| A+ / A | 93-100% | 4.0 |
| A- | 90-92% | 3.7 |
| B+ | 87-89% | 3.3 |
| B | 83-86% | 3.0 |
| B- | 80-82% | 2.7 |
| C+ | 77-79% | 2.3 |
| C | 73-76% | 2.0 |
| C- | 70-72% | 1.7 |
| D | 60-69% | 1.0 |
| F | Below 60% | 0.0 |

How to Calculate Quarter GPA
- List all courses you're taking this quarter with their unit values (usually 4-5 units each).
- Enter your grade (actual or expected) for each course.
- Convert grades to points using the 4.0 scale (A=4.0, B=3.0, C=2.0).
- Multiply each grade point by the course's quarter units.
- Divide total grade points by total quarter units for your quarter GPA.

Frequently Asked Questions
Multiply quarter units by 2/3 (or 0.667). For example, 45 quarter units = 30 semester credits. This is because 3 quarter units ≈ 2 semester credits. Graduate schools and transfer offices use this standard conversion.
Yes! The GPA formula is identical: total grade points ÷ total units. The only difference is that quarter units and semester credits have different values (1 semester credit ≈ 1.5 quarter units). The 4.0 scale works the same way.
Full-time is typically 12-15 quarter units (3-4 courses). To graduate in 4 years at a UC, you need ~45 units per year (180 total). Some students take 16-20 units, but 12 is the minimum for full-time financial aid eligibility.
The impact depends on units taken. If you take 15 units in Fall and 12 in Winter, Fall has more weight in your cumulative GPA. Over time, each individual quarter matters less as you accumulate more units.
Dean's List: 3.5+ at most UCs. Provost's Honors: 3.75+ at some campuses. Major requirements: Many require 2.5-3.0 average in major courses. Graduate school: Aim for 3.3+ cumulative.
Policies vary by school. Many quarter system schools allow grade replacement where only the new grade counts toward GPA. However, both grades may appear on your transcript. Check your school's "repeat course" policy.
Transferring between quarter and semester schools requires unit conversion. Your GPA transfers as-is (it's still on the 4.0 scale), but credits are converted: 45 quarter units = 30 semester credits. This affects progress toward degree requirements.
It depends on perspective. Pros: Faster pace means shorter commitment if you struggle; more GPA data points allow quicker recovery. Cons: Less time to catch up if you fall behind; exams come quickly. Overall difficulty is similar—just structured differently.
Yes, summer quarter courses count toward your cumulative GPA just like Fall, Winter, and Spring. Summer can be a good opportunity to boost your GPA with focused coursework or retakes if needed.
Weight each quarter by its units: (Fall GPA × Fall Units + Winter GPA × Winter Units + Spring GPA × Spring Units) ÷ Total Units. Our calculator above includes an annual GPA feature for this calculation.
