Most course grades are not a simple average of your scores. Homework, quizzes, tests and a final exam usually count for different shares of the total, so a high mark on a small assignment cannot rescue a low mark on a heavily weighted test, and a strong final exam can lift a grade that looked shaky in the middle of the term.
To plan sensibly, list each part of the course with its weight, multiply each score by its weight, and add the results together. That weighted total is the number that matters, and it also shows exactly where extra study will pay off most. If your final exam is worth 30 percent of the course, for example, every point you gain there counts three times as much as a point on a task worth 10 percent.
To see the maths in action, you can average your course grades in one place. Enter your scores and their weights, and you will see your current grade at once, together with what you would need on the remaining work to reach the grade you are aiming for.
Checking the numbers early, rather than in the last week of term, leaves time to change the outcome. A quick calculation now can tell you whether you need a solid pass on the final or a near-perfect one, and that is a much better basis for a study plan than a guess.
