The complete walkthrough

  1. Pick the right calculator

    Open All tools and choose a calculator under Utilities. The suite includes arithmetic, percentages, weighted grades, GPA, fractions and linear equations.

  2. Enter the matching sample

    Use the example line for that calculator. For grades enter scores and course-weight percentages; for GPA enter letter grades and credits.

  3. Calculate and inspect

    Choose Calculate and review the result and displayed steps or formula. The grade tool reports completed work, not a predicted final grade.

  4. Copy or change the values

    Use Copy result, or change the inputs to check a different case. These calculators work on your device and do not save their entries.
