Learning with SuperMemo is based on repetition (see why).

The button Learn (bottom-left in the picture) makes it possible to learn the material stored in SuperMemo :

Repetition cycle

When you press Learn, SuperMemo will ask you to make repetitions (i.e. review due material). In each repetition you will do the following:

  1. Look at the question and try to answer it (mentally or verbally)
  2. Choose Show answer (at the bottom of the screen) to see the correct answer
  3. Compare your response (from Step 1) with the answer displayed on the screen (in Step 2)
  4. Choose a grade that will reflect the accuracy of your response (e.g. Good, Fail, etc.) (look below for grade descriptions)
  5. Choose Next repetition to continue (and go back to Step 1)

The repetition cycle may be shorter. If the repetition is passive (e.g. reading an article), you may immediately jump to the Next repetition stage.

Do not look at the timer, the response time is ignored when measuring your performance.


  • Your first repetitions will usually come up only in 3-5 days after you first add new material. Before they are due, you will only see "Nothing more to learn". This is normal. If Learn does not ask any questions, use Add new to add more material
  • If you keep cycling through items and you never see "Nothing more to learn", you are in the final drill stage and you must start giving passing grades (Good or Bright)


The grades are defined as follows (keyboard shortcuts in parentheses):

Bright (press 5), excellent response
Good (press 4), correct response provided with some hesitation
Pass (press 3), answer recalled with difficulty; perhaps, slightly incorrect


Fail (press 2), wrong response that makes you say I knew it!
Bad (press 1), wrong response; the correct answer seems to be familiar
Null (press 0), complete blackout; you do not even recall ever knowing the answer

Grading tips:

  • Important! You only have to understand the difference between Pass and Fail!
    • Pass and more means remembering!
    • Fail and less means forgetting!
  • your grading will work as long as you always grade yourself consistently and clearly differentiate between Pass and Fail. Over time, you will develop strong habits that will help you select grades automatically without much thinking
  • instead of clicking a grade button you can just press a keyboard shortcut (e.g. 5 to choose Bright or 2 to choose Fail)

Regular repetitions are the key to success with SuperMemo

In SuperMemo you first memorize the material and then review it when the program asks you to do so.

You memorize new material at your own pace but once it is memorized, you must make repetitions exactly as demanded by SuperMemo. This is not a limitation of the program. This is a limitation of human memory!

The power of SuperMemo is in providing the best timing for repetitions. Optimally, you should work with SuperMemo every day! This way you will not accumulate outstanding material and you will not deviate from the optimum schedule of repetitions!

Your repetitions should proceed daily until the following equivalent conditions are met:

  • you see the message: Nothing more to learn
  • Outstanding equals to 0+0 in the statistics window (or simply 0)
  • the second field of the status bar displays (0+0)/x, for example: (0+0)/23 (or simply 0)
  • the progress bar on the status bar becomes blue (or is inactive)

Learning stages

Each day, your learning will proceed in three stages:
  1. Repetitions - reviewing material that has been memorized earlier (to make sure you do not forget it)
  2. Memorizing - if you have time, you can memorize new material by answering Yes to Do you want to learn new material? (this message is suppressed until you memorize your first 100 elements)
  3. Final drill - reviewing material that caused most problems in the first two stages of learning (Skip final drill must be unchecked in Options)

Important! In incremental reading, during the Repetitions stage you will also read new articles and memorize their portions. The other two stages: Memorizing and Final drill are less important. With the help of the priority queue, you can add far more material to your collection than you can possibly review. This is why, in incremental reading, you will often still have lots of outstanding material in the queue at the end of the day
