How do I get info about a student who has withdrawn from my course

From D2L Wiki

When a student withdraws from a course in TitanWeb, they are automatically removed from your D2L course site (over night). If you manually add them to the course, all of their information will reappear. So, for instance, you will have their grades, records of quizzes, etc. This information may be necessary for them to prove that they have no been participating in your class for a certain period of time.
