Setting the Direction
When asking questions in drills, there are two ways to do it: hide side B or hide side A. Depending on the card, you may want to ask questions on only one side, and you can adjust this.
![]() | There are two types of questions: one where you look at side A and guess side B, and one where you look at side B and guess side A. |
![]() | The only questions asked are to look at side A and guess side B. |
![]() | The only questions will be to look at side B and guess side A. |
Drill
In the drills, you are presented with a question with either side A or B of the card hidden, and you have to guess the hidden part. If you get the answer right, you tap the “Pass” button, and if you get it wrong, tap “Fail.”

Test

Learning Level
Each card is assigned a level based on your memorization level. The next question date and time are determined based on your level, allowing for efficient study.
Level | Time interval until next Test |
0 | 10 hours |
1 | 2 days |
2 | 7 days |
3 | 14 days |
4 | 35 days |
5 | 70 days |
6 | 130 days |
About Tests and Levels
In the drill test, if a card passes both “A → B” and “B ← A”, its level will increase by one.
If either card fails, its level will be 0.
Regarding the levels of the newly added cards
New cards are most effectively studied frequently at short intervals. Therefore, a newly created card will only reach the normal level 0 after passing five times as a “new card.” (The question interval for new cards is the same as for level 0.)
