How an C- Affects Your GPA
If you earn an C- in a 3-credit course, that class contributes 1.7 × 3 = 5.1 grade points toward your semester total. Your overall GPA is the sum of all your grade points divided by your total credits.
Is an C- GPA Good?
For High School Students
Close to falling below common graduation thresholds - worth addressing directly with a teacher or counselor.
For College Students
Close to academic probation territory at many schools - check your institution's specific policy.
How Can I Raise My GPA?
This is a good point to get support - talk to an advisor about a concrete improvement plan.
- Meet with your academic advisor to understand exactly where you stand
- Ask about tutoring, writing centers, or other academic support resources
- Focus on your highest-credit classes first since they affect GPA the most
Frequently Asked Questions
What percentage is an C-?
An C- typically corresponds to a 70-72% grade, though the exact range can vary slightly by school.
How many GPA points is an C- worth?
An C- is worth 1.7 points on the standard 4.0 GPA scale.
Is an C- the same at every school?
Not always. Most U.S. schools follow this standard scale, but some use slightly different percentage cutoffs or plus/minus systems - check your school's specific grading policy.
Does an C- in an AP or Honors class count differently?
Yes, on a weighted scale, an C- in an AP, IB, or Honors class is typically worth more points than the standard 1.7. See our guide on how AP and Honors classes affect GPA.
How does an C- affect my cumulative GPA?
It depends on how many credits the course is worth and how many total credits you have. A single grade matters less as your total credit count grows. Use the cumulative GPA calculator to see the exact effect.
Can I improve a grade after it's already posted?
Sometimes - many schools offer retake or grade-replacement options. Check with your registrar, or see our course repeat GPA calculator to estimate the impact of a retake.
What's the next grade up from C-?
The next grade up is C, worth 2.0 GPA points.
Do colleges see my exact letter grades or just my GPA?
Most colleges see both - your full transcript with individual grades, plus your calculated GPA. Some recalculate GPA using their own formula regardless of what your school reports.
Is a plus/minus grading system universal?
No - some schools use only whole letter grades (A, B, C) without pluses or minuses, which changes the GPA scale slightly. Confirm your specific school's system.
