The tests that you have access to as a user can be found in the 'Tests' category of your main menu:
The tests in Drillster are a representation of your level of proficiency in a particular subject at a specific time, namely the time when you created the key.
Tests can be made up of one or more drills and consist of the same questions that are also present in the drills.
How often you may take a particular test is determined by the administrator of the test. It is therefore possible that you only have one attempt to take a test.
The administrator also determines how the final score is calculated, which drills are at the base of the test, which questions are included and which are not. The administrator can also set a review date and choose to use notifications to alert users.
