Hmm... I've always used "sequential" when I sort the Course list, but without thinking that much about it. Good question though.. It does seem like some of the courses are out of sequence if it's meant to chart a learning path from basic to advanced.
I am a new diamond member (couple months). I am enjoying chess mentor, but looking for help as to the order to do the courses.
I have been sorting by easiest to hardest. Is there some method to the madness of the default "sequential" order. I am confused that if you do sequential, you do harder tactics courses before easier ones?
