Heya Christy,
I never did the online courses, but I still would recommend doing the classroom prep classes.
When I was in Law School I could use video prep materials at home or I could go to a classroom and either go to a live class or to see a video (this is in addition to regular class time). I found that breaking out of my usual routine and setting aside this time to go somewhere and be involved with only that work was very helpful.
