Using Khan Academy LSAT videos as a support with other material

Hi, I am currently preparing for the LSAT. I see that the lesson videos for the three sections are a couple years old. Are they still relevant to the recent LSAT exams? Also, is it possible to use those videos as a support while using other prep material? Watching the videos can be helpful for learning the concepts, but I’m also concerned that I don’t see what official LSAT questions the videos used because I don’t want to go over the same questions.
