To study your memory and sleep, use options available in SuperMemo in the following places:

Examples

Tools : Workload

You can use Tools : Workload (Ctrl+W) to inspect the daily and the monthly calendar of repetitions. You can view the number of repetitions scheduled, number of scheduled topics, number of scheduled items, as well as the record of past repetitions, and past retention, or how many new items were memorized.

Daily workload

SuperMemo: Tools : Workload : Daily tab showing the record of repetitions executed over a two-month period

Monthly workload

SuperMemo: Tools : Workload : Monthly tab showing the record of repetitions executed over a three-year period

Tools : Statistics : Analysis

You can use Tools : Statistics : Analysis (Ctrl+Alt+I) to inspect your forgetting curve, daily changes to your measured Forgetting index, your learning overload, and many more:

Forgetting curve

SuperMemo: Tools : Statistics : Analysis : Forgetting Curves graphs for 20 repetition number categories multiplied by 20 A-Factor categories

Daily changes to the measured forgetting index

SuperMemo: Tools : Statistics : Analysis : Use : Efficiency : Forgetting index shows you the changes to the measured forgetting index on individual days

Priorities missed due to overload

Tools : Statistics : Statistics

You can use Tools : Statistics : Statistics to supervise and understand your learning process:

Tools : Statistics : Element data

You can use Tools : Statistics : Element data to inspect learning statistics of a given element:

Element menu : Learning : Show repetition history

You can inspect the history of repetitions for individual elements:

SuperMemo: Repetition history dialog box displaying the history of repetitions for the current element

Tools : Timeline

You can use Tools : Timeline (F12) to optimize the timing of your sleep as well as the timing of your learning:

Sleep and repetitions timeline

Inspect the timeline of repetitions and sleep:

SuperMemo: SuperMemo: Sleep and repetitions timeline displaying repetitions blocks of the current collection (in red) and sleep blocks (in blue)

Look for the best time for learning or sleep (see Timeline for details):

Alertness

See how your brain gradually loses its power during the day:

Two-component sleep model

Look for the time of the day that should give you maximum learning power. See when your learning is not likely to be effective and when you should rather go to sleep:
