Study Scheduling
Study Scheduling
Study scheduling is the choice of when material is returned to. It is not the blocking of hours to study.
A rough prestudy map of the coming lesson covers concepts and relations only. Making one shrinks every later retrieval. Review of material already taught can be caught up. A missed first pass cannot be caught up. When prestudy and review compete for the same two hours, keep prestudy. In practice prestudy is the first thing squeezed out when a week gets busy. It should be the last thing squeezed out. The default failure is treating prestudy as optional and cramming review later.
Core takeaways
- Prestudy outranks review. Review can be caught up later, and a missed first pass cannot.
- Prestudy and spaced retrieval go on the calendar as fixed commitments, not leftover time. A calendar entry works when it names when, where, and how.
- The house ladder has four layers: same-day, one day, one week, one month. It is a workload convenience, not a memory mechanism. Expanding gaps are not established as stronger.
- Set the outer gap from the date the knowledge is needed. The useful gap runs about a fifth to two-fifths of a one-week test delay, and falls to about a twentieth to a tenth of a one-year delay.
- Every retrieval row needs a check against a source, key, or worked example. A session without a key is worth roughly half.
- Interleaving is not universally good. Block vocabulary and definition drills, and interleave problem types, cases, and topic comparisons.
What goes on the calendar
Prestudy and spaced retrieval go on the calendar as fixed commitments. They are not leftover time. A calendar entry works when it names when, where, and how: Saturday 9am, kitchen table, mixed retrieval on this week’s three topics, source closed. “Saturday: revision” does not name those three things. Building a Schedule That Survives covers how that block survives a bad day.
Snowballing a topic means covering the whole of it shallowly first, then adding a layer of depth on each later pass, rather than finishing one section before starting the next. Prestudy covers what that first pass is.
The house ladder has four layers: same-day, one day, one week, one month. It is a workload convenience, not a memory mechanism. Expanding gaps are not established as stronger. Set the outer gap from the date the knowledge is needed. A four-week exam and a nine-month professional exam do not use the same gaps. The useful gap runs about a fifth to two-fifths of a one-week test delay, and falls to about a twentieth to a tenth of a one-year delay. House defaults inside that region: first revision within one to two days, second seven to ten days after the first, third three to four weeks after the second. The ladder will be excessive for some subjects and not enough for others. Spaced Interleaved Retrieval covers the theory and has its own longer four-layer schedule.
The template, row by row
Each row has a different job.
Weekly prestudy (Sunday is a default, not a law). Concepts and how they relate only. No memorising processes, steps, or definitions. A very basic mindmap. The day can move: Saturday or Monday morning is fine. Two weeks of prestudy at a time is allowed, and later a four-to-six-week topic in one go.
End of each weekday. This is the same-day layer. Revise the day’s material into a fuller understanding. Elaborate the map. Be solid on concepts and on how processes work. Still no definition-memorising. Start Flashcards for arbitrary detail, not for concepts.
End of week. Interleaved retrieval covering the last two weeks, not one. Return to weak spots. A gap is anything not recalled, got wrong, or felt unsure about, including things eventually answered. Revision starts with the areas you are least confident about, and finding no gaps is a warning. Begin memorising details by teaching and by self-made questions. Block size: half a day, repeating.
Pockets of time. Run flashcards. They get no session of their own. Completeness of the sitting does not matter. Completeness of the due queue does. Due cards first, extras optional. An incomplete session is better than a skipped session. Microlearning System covers those daily discrete pockets.
End of month. Another interleaved sweep of the month, using a different method from the week’s. The month pass is easy when roughly 80 to 90 percent is still retained at the end-of-week pass, and then it takes a half-day. A hard month pass means that encoding failed or the week pass failed. Block size: a day, a half-day, or a couple of days, repeating. A lot of content adds a mid-month (fortnightly) or mid-week (two-day) review.
Three to four weeks before a test. Heavier retrieval: papers, challenge questions, peer quizzing, plus a patch of the details that keep failing. The window is three to four weeks, not two to three, which is the same window Spaced Interleaved Retrieval uses.
Why prestudy comes before review
Better prestudy shrinks revision time because a prior frame leaves less to forget. No study measures the substitution rate: how many review minutes one prestudy minute saves. The ranking comes from this system, not from a measurement. Review can be caught up later, and prestudy leaves less to catch up on in the first place. The 80 to 90 percent figure is a diagnostic this system uses, not a measured retention rate. The week and month rows run the Revision loop: Test, Target, Teach.
When a schedule does not hold
A schedule that will not hold is not always a priority failure. A plan fails from having no schedule, from vague blocks, from over-packing, from energy, from a high-risk slot, and from a template that is simply wrong for the subject, either excessive or too thin. When those gaps show up, going backward in a skill sequence is the correct response. For a plan that holds on a bad day, see Building a Schedule That Survives. For the sort, see Priority 0+1 System. For the intake, see Task Management. When the block keeps failing, see Procrastination a System Problem.
Cramming and short horizons
Cramming does not guarantee more forgetting at a one- or two-day horizon. The useful gap shrinks as the test delay shrinks, and massed study is not the wrong choice for a test tomorrow. Distributed practice beats massed practice on delayed retention. The claim that this system means more total work is unmeasured.
Checking your answers
Every retrieval row needs a check against a source, key, or worked example. A session without a key is worth roughly half. Do not schedule retrieval for material that has no answer key. Build the key first.
When to interleave and when to block
Interleaving is not universally good. Block vocabulary and definition drills. Interleave problem types, cases, and topic comparisons. The daily flashcard layer is the material that should be blocked rather than interleaved.
Ending a session
A session needs a finish line. Recall each item to a criterion, then stop that item. An open-ended block always feels unfinished.
Judging the template
Give the template a couple of weeks of real use. Scheduling does not have a long learning curve. Each week, reflect on what is not working. Judge the template after two weeks of held blocks. Do not judge it after the first missed Saturday.
Four ways to use this wrongly: a fixed ladder at both ends of the horizon, interleaving on word lists, a due queue treated as optional, and blaming the learner when the template was over-packed. The cost is a half-day every week and a half-day to two days every month, repeating. Stop adding rows when both of these are true: the month pass is hard, and the week pass was not retaining about 80 to 90 percent. In that case, repair encoding or the week pass. Two checks that it is working: prestudy still happens on the busiest week, and due cards are what the pockets clear first.
How to practice this
- Write each study block with a when, a where, and a how: Saturday 9am, kitchen table, mixed retrieval, source closed. Notice whether your entry names all three.
- Book next week’s prestudy, with Sunday as the default day. Map concepts and how they relate, as a very basic mindmap. Notice that you memorise no processes, steps, or definitions.
- At the end of each weekday, revise that day’s material and elaborate the map. Start flashcards for arbitrary detail only. Run them in pockets of time, due cards first.
- At the end of the week, run interleaved retrieval over the last two weeks. Start with the areas you are least confident about. Notice any gap: anything not recalled, got wrong, or felt unsure about.
- At the end of the month, sweep the month with a different method from the week’s. Notice whether the pass is easy or hard. A hard pass means encoding or the week pass failed.
- Three to four weeks before a test, switch to papers, challenge questions, and peer quizzing. Patch the details that keep failing. Notice which details fail again.
