You can modify TestGen tests in the following ways:
Modify test descriptors to change the name, description, or instructions
Modify test content to change question content, add questions, remove questions, reorder questions, or assign or change point values
Modify test-taking options to change the feedback given, review options, time limits, or passwords
Modify test availability to change whether, when, and for how long the test is visible to students
Important: After a student has taken a test, you should make only textual changes to it, for example to correct typos in the question text. Do not add or remove questions, change point values, or add or remove answers.
