If you are speaking about the skills inside the Samsung Members application this is how you earn them.
Skills: Check out a series of articles or videos centered on a particular skill. Each course contains integrative content to help you master a specific feature on your device.
Whoops I sent that too soon. In the members app on the explore page scroll down to recommended then select view more. On the new screen at the top right select browse. On this new screen scroll down a little bit and you'll see a section with the header SKILLS. Select any one of these and a new page will open with articles for you to read. Once you've read all of the articles you will have gained to that skill. I assume some of them would make you take a test but I haven't had to yet. Hope this helps
