Access to any Knowledge Center self-paced course content is limited to 1 year in order to limit the sharing of licenses. When you are nearing your course expiration or if you have already lost access due to expiration, you can request an extension by emailing firstname.lastname@example.org from the email you used to register for the course. As a policy, we grant an additional 30 days automatically on request, starting from the date of request. Prior to granting subsequent additional extensions we do give consideration to account usage. Our primary goal at CSA is to ensure that you are able to complete the course material and use it to prepare for the exam.
