A link to a Certificate is available at the top of the Conclusion Page once you finish the website.
If you’ve already finished the work and logged off, you’ll be taken directly to the Conclusion Page by logging back in.
Every time you click on the link to the Certificate, an extra copy is sent to your email as well. That ensures that you can print that email even if you have trouble printing the Certificate. Courts will accept either one.
If you have any trouble making the link work, it's almost certainly because of an issue with the computer, phone, or other device you're using (such as a block or lack of Adobe Reader). The simple solution is to log on from a different computer.
