I have 14 of the 36 modules done for Lesson 1. I figure I have 3-4 hours in it, but sometimes I'm watching TV and doing some of it later at night when I'm not as sharp. I'm running a bit behind, but I'm also learning Python and, after solutions are presented, I'm going back to my code and adjusting it to be consistent with the class. This helps with my learning the language and will make code less confusing later.
I seem to be running a different version of Python in eclipse than Udacity runs on their website. I would gladly switch the version used in eclipse, but I have not yet found which version of Python they are using. For you Python masters out there, the particular difference is that print in eclipse is a function with nested parentheses in Udacity appears to be a keyword in the language
The stats, so far, have not been difficult at all. All in all, I'm liking the course but, so far, the stats and the code have been relatively easy.
