drip content doubts

hello guys, I'm having a hard time understanding the configuration of drip content. Let me tell you what I need and then please tell me what would be the correct setting:

• let's assume that each class of a course has 60 minutes already considering the video lesson.

I want the student to only go to the next class after this class is finished, that is, that the student watches the entire video. The student should not move to the next lesson without staying in the configured time. The same will apply to classes that have no video. In my current configuration the student could go through the classes, but I want to block this. in no way can the student access the next lesson without finalizing the previous lesson. if you can, show me a prints of this setup thank you
