good course
It's not perfect, (I'm not really sure how you could sexy up some of the math that you must know for the theory portion of the course) but it is an excellent, and free, course for people who are interested in, or need a refresher in analogue electronics.
If you've any doubt about your math and physics background, I'd STRONGLY recommend going through the Electrical Engineering pages on Khan Academy, and knowing those formulas cold before starting in on this course.
Very good course, some of the math is a bit advanced, but the explanations are excellent. Thank you very much for this opportunity. I am eagerly waiting for the part 2!!
