lessons

can someone tell me if im missing something. the lessons have instructors telling that in this tutorial we will be discussing....... then there doesnt seem to be discussing it just goes on to the next instructor and a different part of the lesson, im lost

Not entirely sure, but... If you click on a lesson. Do you notice the red arrow button at the top of the video? That will take you onto the next lesson in the series. There can be 1 to many lessons in a series.

ALSO, it would depend on how you got to that lesson to begin with. If you just did a search and a random click, you may be bringing up lessons that are not in a series perhaps.
