Although I don't have time to correct everyone's assignments - too busy doing that for my RL students - I glanced at a few.
Everybody seems to be doing solid work and really thinking about the issues. :-) Congrats!
As one would expect, levels of achievement vary; not everyone here has the same preparation. From what I have seen so far, the important stuff which needs to be improved *will* be addressed in one or the other of the next few lessons, as planned.
At the end of the mini-course, if there are still outstanding questions to deal with, I will discuss them then, and make note of them for future versions of this course.
Meanwhile, keep up the good work. :-)
