📊 What is GPA?
Grade Point Average (GPA) is a standardized way of measuring academic achievement. It's calculated by dividing the total grade points earned by the total credit hours attempted. Most US colleges use a 4.0 scale, where A = 4.0, B = 3.0, C = 2.0, D = 1.0, and F = 0.0.
🎯 GPA Calculation Formula
GPA = Total Grade Points ÷ Total Credit Hours
Example: If you have:
- Math (A, 4 credits): 4.0 × 4 = 16 points
- English (B+, 3 credits): 3.3 × 3 = 9.9 points
- Science (A-, 3 credits): 3.7 × 3 = 11.1 points
Total: 37 points ÷ 10 credits = 3.70 GPA
📈 Understanding GPA Scales
- 4.0 Scale: Most common in US colleges (A = 4.0)
- Weighted GPA: Gives extra points for honors/AP classes (up to 5.0)
- Plus/Minus System: More precise grading (A+ = 4.3, A- = 3.7)
- Percentage Scale: Some schools use 0-100% instead of letters
Pro Tip: Always check with your school about which scale they use and whether they calculate weighted or unweighted GPA for transcripts.
💡 Tips to Improve Your GPA
- Focus on high-credit classes: They have more impact on your GPA
- Retake failed classes: Many schools replace the old grade
- Take easier electives: Balance difficult core classes
- Seek help early: Don't wait until you're failing to get tutoring
- Attend all classes: Participation often affects grades
- Build relationships: Connect with professors for better support
⚠️ Important GPA Considerations
- Different schools may calculate GPA differently
- Some schools don't count + and - grades
- Pass/Fail classes usually don't affect GPA
- Withdrawn classes (W) typically don't impact GPA
- Transfer credits may be calculated separately
- Graduate schools often look at major GPA separately
