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?

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.

you know I can't get anyone from chess.com to answer this question...I have tried 3 different sources, including forums started by staff to answer chess mentor questions - who then ignore questions...frustrating.

There seems to be no reason to stay in this group...

Go through the study plans! In the prescribed order. I think this is the best order. And then, I hope, the advance package comes.
