I just signed up a week ago and I have been doing video lessons and labs for Linux+. I think the labs are a great tool, but there are dozens of labs that go with the course, which makes it difficult to figure out which lab goes with the video lesson I just completed.
It would be much easier if I were, for example, doing the Lesson on Command-line in Linux and after watching the video I clicked on Virtual Labs and only 1 or 2 labs popped up related to the topic so that I could put the lesson to practical use.
Sometimes the labs don't match up with the names of the lesson either, which makes it difficult to get the correct lab.
Just a suggestion... keep up the great work all!
