Frequently asked questions
How is a weighted grade calculated?
Multiply each grade by its weight and add the results. If the weights do not add up to 100%, the total is also divided by the sum of the weights.
How are letter grades converted?
Each letter is turned into a typical percentage (for example A = 95, B = 85, C = 75) before averaging. Your school may use different cut-offs.
What does additional grade needed mean?
It is the average score you must get on the remaining part of the course (the weight not yet entered) to reach your target.
