What do I gain by creating groups of similar questions?

Creating groups of similar questions has advantages for the teacher:

1. Your materials will be better organized when similar questions in your preparations are grouped rather than listed individually.

2. A gorup of questions can be added to a test. The system will randomly pick one or more questions from the group to add to the test. Thus, each student can have a different test, but the tests will still contain the same type of questions.
