Andy, the labs and courses were not designed that way.
It's up to you to decide when you choose to do the labs. This take a little more on your part but you can choose to watch and then decided which lab to do.
Some choose to do the videos, then go back and do the labs. Or they may watch several videos and then search out labs that match.
But our product is a merging of 2 companies. We may get to the point where the labs align exactly with the video content but we're not there yet. This shouldn't prevent you for being able to use them to help supplement your study in CEH.
