Your grade in each class contributes to your semester GPA, which reflects your academic performance. Understanding how a single grade impacts your GPA helps you plan and set goals.
Semester GPA is based on a 4.0 scale:
Steps to calculate:
A low grade, especially in a high-credit class, can pull down your GPA, while a high grade can boost it.
Example: Let’s say you’re taking four classes this semester, each worth 1 credit: Math (B), English (A), Science (C), and History (current grade: D). Your GPA without History is (3.0 + 4.0 + 2.0) / 3 = 3.0. If your current grade in History is a D (1.0), your semester GPA becomes (3.0 + 4.0 + 2.0 + 1.0) / 4 = 2.5—a significant drop.
If History were a B (3.0) instead, your GPA would be (3.0 + 4.0 + 2.0 + 3.0) / 4 = 3.0, maintaining your average.
High-Credit Classes: If a class is worth more credits (e.g., 2 credits), its grade has double the impact. Focus on these to protect your GPA.
To see how your current grade affects your GPA: List your grades and credits for each class. Input them into our High School GPA Calculator at Grade-Calculator.io. Test scenarios (e.g., “What if I get a B?”) to plan ahead.
