GPA calculator
Your GPA is the credit-weighted average of your course grade points on the 4.0 scale. Type each course as a letter grade or a percentage with its credit weight and this page works out both the weighted GPA, which is how a transcript normally averages, and the unweighted average. Nothing you type leaves your browser and there is no account.

Ontario percentage to GPA
An Ontario percentage converts to a 4.0-scale GPA through the OUAC Undergraduate Grade Conversion Table, which OMSAS uses for medical-school applications: 90 and above is 4.0, 85–89 is 3.9, 80–84 is 3.7, and each band below follows the table shown on this page. Enter a mark and the matching GPA and letter appear beside it. The whole scale is printed underneath so you can check the band yourself.

Study schedule planner
Give this planner your exams, their dates and the hours you can study each day, and it builds a day-by-day plan from today to your last exam, giving the nearest exam the largest share of each day and passing its hours on once it is over. The plan is shown as a table and can be downloaded as an .ics file that opens in Apple Calendar, Google Calendar or Outlook. It runs entirely in your browser.
Open the study schedule plannerWhen arithmetic is not the problem
A calculator tells you where you stand; it cannot move the number. CANtutor AI works through the course with you by voice on a shared whiteboard, grades a draft against the rubric your teacher actually set, and builds the study plan from your own lecture or course material.
