To make sure you remember well, SuperMemo will test your memory. Each little test will include these steps:

1. Answering a question (mentally or verbally)
2. Clicking Show answer (or Enter) to see the correct answer
3. Comparing your response (from Step 1) with the answer displayed on the screen (in Step 2)
4. Choosing a grade reflecting how well you remember (e.g. Good if you remember, Fail if you do not remember, etc.)
5. Clicking Next repetition (or Enter)

Let's test it on an example (press Enter)
