Six tools built for classwork, study sessions, and group projects.
Add each course, its credit hours, and letter grade.
Add graded categories with a weight (%) and your score (%) in each.
Switch between the three most common percentage problems.
25 minutes of focus, then a short break. Repeats automatically.
Count up while you study, then log the session.
| Subject | Duration | Date |
|---|
Paste names, one per line, then pick.
Each tool above runs entirely in your browser, so course names, grades, and your study log stay on your own device.
An unweighted GPA gives every course the same value regardless of difficulty. A weighted GPA, which this calculator produces, factors in credit hours so a 4-credit course counts for more than a 1-credit course in your overall average.
The grade calculator turns each category's weight into a share of your final grade. If the weights don't total 100%, the categories you've entered don't represent your whole grade yet, so the result will be off until they do.
On the standard 4.0 scale, a 3.5 or higher is generally considered strong, and a 3.7+ is competitive for selective programs. What counts as "good" still depends on your school's grading scale and the courses you're taking.
Working in short, focused intervals with regular breaks reduces mental fatigue and makes it easier to sustain concentration over a long study session, rather than burning out partway through.
Everything runs locally in your browser. Your study log is kept only on your own device so you can review past sessions, and none of your course, grade, or name-list data is sent anywhere.
