course, i enjoyed it very much, but be warned, you must have basic knowledge of basic phisics and math, understanding how derivatives work is esential. some people claim the teacher explains poorly, THIS SI UNTRUE explanations are very good but without understanding math and phisics you wont be able to follow so those who complain must grab a book first and git good. Also it has somwhat poor subtitles due to the writers sloppy work, some words apear out of context and some times an [INAUDIBLE] message apears, however I had no problems at all understanding professorYang-Hann Kim.
