How the schedule is built

For each subject, the number of sessions is the hours you want to study divided by the session length. The sessions are then spaced evenly between your start date and the day before the exam instead of being crammed at the end, and the last ones become final reviews.

\[ \begin{gathered} \text{sessions} = \dfrac{\text{hours} \times 60}{\text{session length}} ,\ \text{rounded up} \\ \text{spacing} = \dfrac{\text{days available}}{\text{sessions} - 1} \end{gathered} \]

A day never exceeds the time you entered for that weekday, and if a subject already has a session that day, the next one moves to another day.

How many hours per subject

Hard or high-credit subjectHard12 hours

If you leave the hours empty, the planner uses these values based on the difficulty you pick.

Rules of good revision

  • Use 45 to 60 minute sessions with a real break.
  • Mix subjects across the week instead of one subject per day.
  • Keep the day before an exam for light review and sleep, not new material.
  • Review notes a few days after learning them: that is what builds memory.

3 real-life examples

1

Finals in six weeks

Calculus (12 hours), History (10) and Chemistry (8) with 1 hour on weekdays and 2 on weekends. With 1-hour sessions, 30 sessions are spread over 42 days, with final reviews right before each exam.

2

A midterm in ten days

One subject of 8 hours at 1 hour a day: 8 sessions over 10 days, one every day or two, with a final review the day before the exam.

3

An overloaded plan

You ask for 30 hours in 5 days with 2 hours a day available: the planner schedules 10 hours and warns « 20 hours missing ». You can then pick which subjects to prioritize.

Frequently asked questions

How do I make a study schedule?
List your exams, estimate the hours per subject, spread the sessions over several weeks and keep final reviews before each test. This planner does the math for you.
How long should I study before an exam?
Plan 4 to 6 weeks for finals, the SAT or AP exams, and 2 to 3 weeks for a midterm. The earlier you start, the shorter each session can be.
Why space out study sessions?
Reviewing an idea at regular intervals fixes it far better than one long session. This is called spaced repetition.
What if the planner says time is missing?
Add free hours on weekends, reduce the hours for your easiest subject or start earlier. A realistic plan beats a perfect one.
