I know some people are new and I just spent an hour or more fixing my progress so that it would register correctly on the site. For all the newbies, like myself, who just finished Fundamentals 1, I now KNOW what to do to make sure your progress gets marked correctly. When you finish a lesson, at the right side of your screen you will have a progress bar that shows 100% and under it a bar that says I'm Done. To mark your progress so it registers, click the bar that says I'm Done. It will then say: Mark it Done, and under it says Share on Guitar Tricks. You must click on I'm done a second time. When the bars read I'm Done! Not Done? that is what it should read for progress to be registered. If your two bars show 100% and the one under shows I'm done: you're NOT Done. Hope this helps. Happy to be moving on to Fundamentals 2.
