Semester Grade Calculator
The whole term, one running number.
A semester grade calculator keeps a running weighted average as assignments land. Enter each score with its weight, and the current grade updates: quizzes 80 at 20 percent, midterm 90 at 30 percent, homework 95 at 30 percent gives 89.4 percent with 20 percent of the grade still to come. Pair it with the final-score tab to plan the rest of the term.
Running total vs final answer
Early in the term the running grade swings wildly because few points are banked. Late in the term it barely moves because most weight is locked in. Both readings are correct; they just mean different things.
Use the running total to spot trouble early, when there is still weight left to fix it. A bad midterm in week 6 is actionable; the same grade in week 15 is a eulogy.
Projecting the finish
Once you know the current grade and the remaining weight, the final-needed formula tells you what the rest of the term must average. If remaining work is 20 percent and you hold 89.4, an 86 average on the rest lands you near 88.7.
Run best, likely, and worst cases. Three scenarios beat one anxious guess.
Across multiple courses
For a whole semester across courses, weight each course grade by its credit hours, exactly like GPA math. A 4-credit A and a 3-credit B average to (16 + 9) / 7 = 3.57 on the 4.0 scale, not 3.5.
This is where the GPA calculator earns its keep: semester tracking feeds straight into cumulative GPA planning.

Semester grade questions
How do I calculate my grade for the whole semester?
Enter each score with its syllabus weight; the weighted average is your current semester grade. Update it as new grades land, and use the final-needed formula to plan what remains.
Why did my grade barely move after a good quiz?
Each new score moves the average in proportion to its weight relative to everything banked so far. With 80 percent of the grade decided, even a perfect quiz on the remaining 20 percent can only nudge the total.
How do I combine grades from multiple classes?
Multiply each course grade by its credit hours, add the products, and divide by total hours. A 4-credit A outweighs a 3-credit B, which a straight average would miss.
