Study Hour Planner

Allocates a target weekly study budget across multiple subjects, weighting by perceived difficulty and credit hours. Common heuristics suggest 2–3 study hours per credit hour for university coursework.

Outputs a per-subject hour count plus suggested daily distribution across a chosen number of study days.

The 2-3-hours-per-credit guideline is a long-standing US university norm reflected in federal financial aid definitions: a 'credit hour' represents roughly one hour of class plus two of independent work per week, multiplied across a 15-week semester. A 3-credit course implies 6-9 study hours weekly; a 15-credit course load implies 30-45 study hours. Combined with class time, this approaches a 60-hour week, which is why university coursework is treated as a full-time commitment in degree planning.

A worked example: a student takes 12 credits across four courses (Calculus, Literature, Chemistry, Spanish) and assigns difficulty multipliers of 1.5, 1.0, 1.3, and 0.8 respectively (Calculus and Chemistry being problem-set-heavy, Spanish requiring less new conceptual learning for a heritage speaker). Raw credit-weighted hours at 2.5 per credit are 7.5 per course. Applying difficulty: 11.25, 7.5, 9.75, 6.0 = 34.5 total weekly hours. Distributed across 6 study days, this is roughly 5.75 hours per day. The schedule weighs heavier on Calculus and Chemistry days, lighter on Spanish-only days.

Limitations come from the fixed-formula approach. Real study time scales with the specific assignment load that week, not a constant rate. A literature week with two essays due needs vastly more time than a literature week of just reading. Math and STEM courses often follow the opposite pattern: front-loaded conceptual learning early in the semester, lighter near finals, or the reverse depending on whether the course assesses by problem sets or by cumulative exams. Spaced repetition research (Ebbinghaus's forgetting curve, modern flashcard literature) suggests memorization-heavy work benefits from short daily sessions over a long horizon; the planner does not enforce this and may suggest concentrated bursts that perform worse for retention.

The planner is best used as a starting framework that gets adjusted weekly based on actual completion rate. Treating the initial allocation as a contract leads to either guilt-driven overwork (the schedule says 9 hours and only 6 happened) or complacent under-allocation (the 9 hours got done, but the assignment still isn't complete). The right cadence is to plan, observe, and re-budget weekly.
