I am on the wait list for the ProGen online study group. I expected to start soon, perhaps Feb 2018. I got an email that the program is being changed considerably. Instead of an 18 month program, it will be rewritten to a 12 month program, and there will be no Feb 2018 group while they revamp the homework assignments. The new 12 month program should start up on schedule and continue as scheduled starting with the next June 2018 group. I anticipate starting in June, or perhaps October.
