How GPA is Calculated
Semester GPA = Σ (Grade Points × Credits) / Σ Credits Grade Points = Credit Hours × Grade Value Cumulative GPA = (Previous GPA × Previous Credits + Semester Points) / (Previous Credits + Semester Credits) Grade scale: A/A+ = 4.0 | A- = 3.7 | B+ = 3.3 | B = 3.0 | B- = 2.7 | C+ = 2.3 | C = 2.0 | C- = 1.7 | D+ = 1.3 | D = 1.0 | F = 0.0

Frequently Asked Questions
What GPA do I need for graduate school?
Most graduate programs want 3.0 or above. Competitive programs (top MBA, law, medical) typically look for 3.5+. However, GPA is just one factor — test scores, recommendations, and experience also matter significantly.
What's the difference between weighted and unweighted GPA?
Unweighted GPA: all classes treated equally (A = 4.0 max). Weighted GPA: harder classes (AP, IB, Honors) can earn above 4.0 (e.g., A in AP = 5.0). Colleges often recalculate GPAs on their own scale regardless.
Can I raise my GPA significantly in one semester?
It depends on how many credits you've completed. Early in college, one strong semester has more impact. After 60+ credits, your cumulative GPA moves slowly — each semester accounts for a smaller share of the total.
