Use this page when the decision starts with a course grade, category weight, exam target, or study plan. The calculators turn syllabus numbers into planning estimates, then the guides explain what can break the simple model.
This index groups working calculators with the supporting notes that explain formulas, assumptions, privacy, and limits. It is meant to be a starting page, not a thin list of links.
Each calculator below has an internal detail page and a direct browser-based tool page.

A student currently has 74% in a class, wants to finish with at least 80%, and has one final exam plus a short project left. The first question is not how many hours to study. It is whether the grade target is mathematically realistic.
Takeaway: Grade calculators define the target; planning calculators help decide whether the remaining time supports that target.
These pages explain assumptions, examples, common mistakes, and privacy handling.
A plain-English explanation of the final grade calculator formula, including examples, edge cases, and course-rule limitations.
Student ToolsLearn how weighted grade calculators combine category scores, why weights must be checked, and when syllabus rules can change the estimate.
Student ToolsLearn the most common mistakes students make when using final grade and weighted grade calculators, with examples for exam weight, curves, dropped scores, and unrealistic targets.
Student ToolsA student-focused guide to using grade, GPA, deadline, and study time calculators without mistaking estimates for official academic records.
Open the final grade calculator if you know your current grade, target, and final exam weight. Use the weighted grade calculator if your class is split into categories.
No. These calculators are for planning. Your instructor, syllabus, and official school system remain the source of truth.
