You have 90 days from your date of enrollment to complete a course and retrieve your certificate. The classes are self-paced so you can take them at your convenience.
If you do not complete the class within 90 days, you will have to repurchase the course to gain access. After the 90 day period, records are purged from the server, so please be sure to downloan or print out your certificate. It will NOT be available after the 90 day period.
