Homework Time Per Subject Planner

Allocate your total available homework time across subjects based on the number of assignments and difficulty level of each subject.

Total Available Homework Time (minutes)

Enter up to 6 subjects:

Subject Name Assignments (#) Difficulty (1–5)

#### Formula

Weighti = Assignmentsi × Difficultyi Total Weight = Σ (Assignmentsj × Difficultyj) Allocated Timei = (Weighti ÷ Total Weight) × Total Available Time Time per Assignmenti = Allocated Timei ÷ Assignmentsi

Each subject receives a share of the total homework time proportional to its weighted load, which is the product of the number of assignments and the difficulty rating (1 = very easy, 5 = very hard). A subject with 3 assignments at difficulty 4 receives twice the time of a subject with 3 assignments at difficulty 2.
