Most syllabi split the course grade into categories, such as homework, quizzes, a midterm, a project and the final exam, each worth a set share. This calculator does the two sums students ask about most: what is my grade right now, and what do I need on the final.
Your grade now. Each category's score is multiplied by its weight, the products are added, and the total is divided by the weights that have a score. A category with no marks yet is left out instead of counting as zero, which is how most online grade books show a running grade. Scores can be typed as a percentage (92) or as points (45/50, or 18 of 20).
The final exam. With the final worth f of the course, the score needed is (target − current × (1 − f)) ÷ f. The page shows it for the grade you chose and for every letter on the scale, and also what your grade becomes for any exam score you try. A needed score above 100% means the target cannot be reached without extra credit; zero or below means it is already secure.
The rest of the article, and all 6 questions about Grade Calculator, are on the Grade Calculator page.
Multiply each category score by its weight, add the results and divide by the total weight of the categories that have a score. Homework at 92% worth 20% and a midterm at 78% worth 25% give (20 × 92 + 25 × 78) ÷ 45 = 84.22%. The calculator does the same for up to 30 categories.
Subtract your current grade times the share of the course already done from the target, then divide by the final's weight. At 85% with a final worth 30%, a B at 80% needs (80 − 85 × 0.7) ÷ 0.3 = 68.33%. The page lists the score needed for every letter on your scale.
Yes. Type a score as 45/50, 45 / 50 or 18 of 20 and the calculator converts it to a percentage before weighting. Percentages can be typed as 92 or 92%. Scores above 100, from extra credit, are accepted. A category left empty is treated as not graded yet, never as zero.
Categories without a score yet are simply left out, and the grade is the weighted average of the ones that have marks. Enter the final exam's weight separately in the final exam box. When the category weights plus the final add up to something other than 100%, the page says so, because a syllabus weight was probably missed.
