Key Takeaways
- Weighted Grade Formula: Overall % = Sum(Grade x Weight) / Sum(Weights).
- Final Exam Target Formula: Score Needed = [Desired Grade - (Current Grade x (1 - Final Weight))] / Final Weight.
- A weighted category system means high-weight assignments (like a 35% midterm) impact GPA more than dozens of low-weight homework sets.

Divide the weighted total by the sum of currently completed weights. This normalizes your current standing relative to finished coursework.
What is the standard 4.0 GPA letter grade scale?
Typically: 93-100% = A (4.0), 90-92% = A- (3.7), 87-89% = B+ (3.3), 83-86% = B (3.0), 80-82% = B- (2.7), 77-79% = C+ (2.3), 70-76% = C (2.0), 60-69% = D (1.0), and below 60% = F (0.0).
