The Study Calendar That Stops Treating Sunday as a Rescue Mission
Spacing gives you more than one encounter with an idea instead of asking a single marathon session to do everything.

Sunday's plan says “revise the whole chapter.” The chapter has been untouched all week. By evening, it feels familiar, but there is no room left to discover what needs another attempt.
Schedule returns, not only duration
The Learning Scientists describe spaced practice as spreading study over time. A useful original plan gives one topic several short visits: an initial explanation, a later recall attempt and another check after a gap.

Choose dates that fit your actual timetable. Do not copy a complicated spacing schedule you cannot maintain. The important change is that the subject returns before the deadline rather than occupying one heroic block just before it.
Leave a question for the next visit
At the end of each session, write what you want to test next time. That might be a definition, a worked step or the difference between two ideas. The note makes the next session easier to begin.
Spacing is not permission to keep every session superficial. Each visit still needs useful work and feedback. Its practical advantage is that forgetting and uncertainty become visible while you still have time to respond. Sunday can then become one part of a plan instead of the emergency department for the whole week's learning.
