About Canvas Grades & GPA Calculator: Missing Assignments, Finals & Due Dates

See every Canvas grade, every due date, and exactly what you need on the final - in one dashboard. Works even when professors disable Canvas grade totals. Free, no account, no tracking. Canvas makes you click into every course just to check a grade. Half your professors hide grade totals. Canvas Power Tools fixes that. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHAT YOU GET ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ EVERY GRADE IN ONE VIEW See your current percentage, letter grade, and credit hours for every course on a single dashboard. Sort by risk, due dates, or course. No more hunting through six class pages to figure out where you stand. WORKS WHEN TOTALS ARE DISABLED Most grade extensions break when professors hide Canvas totals. Power Tools calculates your real grade anyway using the same weighted average formula Canvas uses internally. The killer feature nobody else has. GPA CALCULATOR + FINAL EXAM TARGETS Instant targets tell you exactly what score you need on remaining work to finish each class with an A, A-, B, or C. Works for weighted and points-based courses. WHAT-IF GRADE SIMULATOR Drag sliders on upcoming assignments. Watch your grade change in real time. See how much a 70 on the final actually hurts before you take it. DUE DATE PLANNER Every assignment across every class, grouped by Due Today, This Week, and Coming Up. One list, not fifteen course pages. FULL CALENDAR VIEW Month grid with every Canvas due date color-coded by course. Click a day to see everything due. Your workload at a glance. SMART DROP DETECTION Auto-detects courses that drop your lowest N assignments. Simulates which ones you can skip without hurting your grade. CURVE DETECTION Flags classes that look curved so you don't panic at a 58% that's actually above average. GRADE + WEIGHT OVERRIDES Professor hasn't published assignment group weights? Type your own. Wrong grade entered? Override it. Math recalculates automatically. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHY STUDENTS CHOOSE IT ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ • 100% FREE. No paywall. No premium tier.
