Great stuff Bob - now do we need to post both 1st week and 4th week submissions for all lessons to be eligible to be examined?
Geoff and Mark;
The short answer; no. However, you do need to fully participate in each lesson. That means you need to submit all of the required assignments at least once. I've listed the required assignments at the top of each index. I will periodically update the indexes from time to time as students fill in the missing blanks.
Last year's exams (2010-2011) took place between the time lesson #9 and lesson #10 were published. To qualify, you needed to have fully participated in at least seven of the lessons for the class you wanted to take an exam (D01-D03). I don't know if qualifying will change this year but you might want to prepare ahead of time by catching up on any missed assignments.
