What does a study time calculator do?
This is a planning tool, not a prediction of academic performance. It converts the study-hours-per-credit target you choose into a course-by-course weekly estimate and adjusts that estimate for the difficulty level you assign.
Choose a realistic base ratio
Different courses, students and weeks can require very different amounts of independent work. The calculator therefore does not hard-code one universal rule. Enter a base number of study hours per credit that reflects your expectations, then use difficulty settings to vary individual courses.
How difficulty multipliers work
Light is 0.75 times the base, Standard is 1.0, Challenging is 1.25, and Intensive is 1.5. These are scheduling multipliers only. They do not claim to measure course difficulty objectively.
Compare the estimate with available time
The result compares estimated weekly study hours with the availability you enter. A negative gap means the modeled plan needs more time than you currently set aside, which can prompt you to adjust the ratio, course assumptions, study days or schedule.
