I would suggest using the lesson time as is, schedule lessons (or chapters) on your calendar not the whole course. A full course could take several hours just to watch.
To effectively learn from a lesson/course, you will need to pause the video and practice what is being taught.
Try not to over schedule, schedule more time than the lesson indicates, I would go as far as doubling the lesson length.
If you have time to spare, use it to practice, don’t get ahead of yourself. It’s easy to say “I completed my schedule and I have half hour to spare, I’ll watch another lesson or two”, It is better to use that time to practice, than rush through another two lessons.
