Once you register and pay for a course, you will be emailed an invoice receipt for your records. Check your junk mail folder if you did not receive the email. Similarly, once you earn a certificate of achievement and digital certificate, you will receive an email with a link to obtain them. You can also access receipts or certificates by signing into the site, clicking on your name, and selecting “My Account”. Certificates and receipts continue to be available through your account even after your access to a course expires.
