What is spaced repetition? A practical study schedule
Learn how spaced repetition and active recall work together. Try a seven-review schedule for your notes, with concrete examples and research references.
Spaced repetition means revisiting learning material across separate study sessions. Active recall is what you do during each review: try to retrieve the answer before checking your notes. A schedule helps you return; questions give you something to retrieve.

Start with one small learning goal
Choose something you can explain or apply in a few minutes, such as why binary search needs sorted input. Avoid putting an entire course into one knowledge item: you will struggle to tell which parts you remember.
Write a short note, then two or three questions. A useful question names a specific task, such as explaining a condition, comparing two ideas, or solving a small example.
An example spaced repetition schedule
Knowloop schedules reviews 20 minutes, 1 day, 2 days, 4 days, 7 days, 15 days and 30 days after the original learning time. These are cumulative offsets from learning, not gaps added after each review.
This is a fixed starting routine. It is not a scientifically optimal timetable for every person or subject, and it does not implement adaptive algorithms such as FSRS.
| Review | After learning | Example date and time |
|---|---|---|
| 1 | 20 minutes | Oct 24, 09:20 |
| 2 | 1 day | Oct 25, 09:00 |
| 3 | 2 days | Oct 26, 09:00 |
| 4 | 4 days | Oct 28, 09:00 |
| 5 | 7 days | Oct 31, 09:00 |
| 6 | 15 days | Nov 8, 09:00 |
| 7 | 30 days | Nov 23, 09:00 |
What to do when a review is due
Close the source and answer a question aloud or in writing. Reveal the reference answer, then check the original passage. If you missed a condition or confused two concepts, write down the exact gap.
- Remembered: explain the idea without copying the note.
- Unsure: identify what you could not justify.
- Not remembered: reread the relevant passage, then try again without looking.
What the research supports—and what this schedule adds
Cepeda and colleagues’ meta-analysis supports distributing practice over time; useful spacing depends in part on how long information needs to be retained. It does not validate Knowloop’s exact seven offsets.
The practical choice here is a predictable routine. For an exam next week, check coverage against the exam date yourself; the tool does not compress a 30-day plan into seven days.
If you miss a review, resume with the next useful question
Start with the most important overdue item, answer its questions and inspect what you missed. A missed day does not require rereading every note from scratch.
In Knowloop, overdue tasks remain available and later dates stay fixed. Your difficulty feedback records how the session went; it does not automatically reschedule future reviews.

Common questions
Do I need flashcards for spaced repetition?
No. You can recall an explanation, solve a problem or reconstruct a diagram. Knowloop supports optional AI-generated or manually written question-and-answer cards alongside notes.
Is this an adaptive spaced repetition system?
No. Knowloop uses seven fixed offsets from learning. Review feedback is recorded but does not change the remaining dates.
