NB: If you would like to retake a course in order to receive an updated certificate, you will need to repurchase it and request that we delete your previous test data for that specific course by emailing us at info@lerc.org. Once we have received your request and deleted the old test data we will contact you by email and you will be free to retake the course quizzes and access your updated certificate. Thank you.
