Study Hours Planner FAQ
How does the study hours planner work?
Study days are the days left, reduced for weekly rest days and for the buffer you keep free. Hours needed per day is total hours divided by study days. Each subject’s daily share is its hours divided by study days.
How do I estimate the hours a subject needs?
Think about chapters, practice and revision. Many students plan roughly the hours per chapter times the number of chapters, then add practice papers. Adjust after the first week.
Why keep a buffer?
Illness, delays and weak topics always eat time. A buffer of 10% or more keeps a slip from ruining the whole plan.
Is this study hours planner free and private?
Yes. It is free with no sign-up, and the calculation happens on your device, so your numbers are never sent to a server.
