40-Minute Session Example
If you only have 40 minutes today, start with ‘Mix three already learned problem types’. Then record the mixed set result and separate correct items from confused items. Use the final five minutes to write one question that starts the next review. That small closing record prevents the next session from becoming setup time again.

The record does not need to be long. Filling three fields, mixed set, method choice, and confusion pair, is enough for one session. Move correct items to a longer interval, tag confused items with a short reason, and put missed items at the top of the next session. This keeps the next study block from starting with setup work.
Checklist
- Before starting, define the mixed set output for today.
- Before ending, check method choice and mark the next review item.
- Keep time spent, correct items, and missed items in one table.
