This is the selection of the questions that appear in the test. Default setting is all questions (Complete), but by changing this setting to 'Previously made mistakes', the questions that were answered wrongly in previous tests are included only.
All the options:
Complete
This is the default 'Selection'. All questions appear in the test.
Previously made mistakes
All questions are included that were answered wrong once.
Make selection
It is possible to make a selection. This is used for small subsets of a big list. The selection screen will be displayed. To make a selection fast, use the arrow buttons and the space bar to select/unselect questions.
Top 10 problem questions
The ten most difficult questions of the list. This number can be modified in the settings dialog.
Random selection of 10 questions
Make a real test, to see if you know the list well-enough. Teach2000 selects ten questions randomly.
Only newly added questions
If you added questions to the test, you can practise them only by setting this option.
Leave questions you already memorized
If a question has been answered correctly four times in a row, it won't appear in the test when this option is set.
