The course Rook and Other Endgames is full of repeat lessons, I have been going through it and of the 140 lessons offered in this course there are way less unique ones.

Some lessons are repeated several times.  All the way down the list.  Other than this I havem't had any provlems and I love this program

"Endings, Openings, a Taste of the Middle" has the same problem.  Maybe all the repetition actually helps. 

I can understand maybe doing a lesson and coming back to it after a whack more lessons to see if you actually learned it.. but the course I posted has the easiest lessons repeated over and over again right after eachother so out of 20 lessons you really only do four 5 times each lol.  and they are all basic

Right, the repetition of some of the most basic (and important!) concepts is intentional so that the student will surely know and remember these critical ideas.
