I am taking this course right now and am on week 5 in the course outline. I just wanted to warn others that the instructor is off by a week in his lectures. The midterm quiz comes at the end of week 4 but includes questions relating to week 5. In week 5 lectures, he calls it week 4 in the videos. So, you should skip the midterm in week 4 and go forward to week 5 then go back to the quiz after finishing week 5, if it will let you.
Other than that, this is a great course. The instructor is very easy to understand and is quite personable. Since it is an introductory course, it covers a wide overview. So, even though he jumps through a lot of different areas, the lectures flow nicely and give a lot of detail without going off too far into tangents.
