|
|
|
-* One exercise may contain different types of answers (unique or multiple selection,
|
|
|
-* matching, fill in blanks, free answer, hot-spot).
|
|
|
-*
|
|
|
-* Questions are selected randomly or not.
|
|
|
-*
|
|
|
-* When the user has answered all questions and clicks on the button "Ok",
|
|
|
-* it goes to exercise_result.php
