Understood.
However, I disagree with your principal that "I believe the value of the review course is in their reference material (aka study material) more than the presentation of that material in the classroom." I believe there are many two types of students: independent studiers and those that need instruction. Other posts will back this up that 'instructor comments are invaluable.' Speaking from experience, I know I was able to answer to questions directly from recall of something an instructor said that was not in the reference notes. The point I am trying to make is that some students may need to be taught, some may be out of school for a while and may not remember by simply reading notes and others may just simply respond better to instruction versus independent study. That's it. I believe there is more to rating a review course than just it's notes.
I do not want to get into defending one course versus the other.
