  description

  Instantly know your grade and what you need.
  
    Canvas Grade Calculator shows you exactly where you stand in every Canvas course — even when your professor has disabled grade totals.
  
    FEATURES
  
    ▸ Your Real Grade, Always Visible
    See your current percentage and letter grade calculated in real time from your Canvas grades page.
    Works with both weighted and unweighted (points-based) courses.
  
    ▸ "What Do I Need?" Calculator
    Pick your target grade (A through D, with plus/minus options) and instantly see what score you need to
    average on your remaining assignments. No guessing, no spreadsheets.
  
    ▸ What-If Simulator
    Drag sliders to simulate scores on upcoming assignments and watch your grade change in real time. See
    exactly how each assignment affects your final grade.
  
    ▸ Assignment Group Breakdown
    See your percentage in each assignment group (Homework, Exams, Quizzes, etc.) with visual progress bars
     and weight percentages.
  
    ▸ Works When Totals Are Disabled
    Many professors disable Canvas's built-in grade totals. This extension calculates your grade anyway.
