The post of mine that you are referring to includes a couple of links, including those in a referenced prior post of mine about two specific Audiology Online Courses.
So, in the post to which you’re replying, you’ll find a link that leads to a Phonak course filter search. In the referenced post, there are links to two specific courses.
Whichever link you follow, when you find a course that sounds interesting, somewhere in the description, there will be a REGISTER button. When you click that button, you’ll be prompted to log in to Audiology Online if you’re already a member or sign up for a free Audiology Online membership if you’re not. Here’s what the REGISTER screen looks like when you click the button for a course you’re interested in:

You can take a course, download the handouts, etc., at no expense, the last time I tried. When you’ve completed the course, Audiology Online will nag you to take a quiz and pay a fee to get CEU credits, but you can only do that if you are a hearing care professional. Just ignore the nags.
