Reinforcing what @eddieb and @Martin_K have said, in order to track your progress in the school of Pipsology, simply click on the "Yes" option found on this box at the end of each lesson.
Once you've done that and you decide to proceed to the next lesson, you'll see that your tracker has been updated.
You'll be able to easily track your progress from here.
I hope that answers your question! Feel free to shoot us a PM should you have any more. We'll be happy to help you.
