This is a great course for non-majors who are learning programming for the first time. I am currently taking the professor's C++ course, but Mr. Ttaebae's course is a course that I would recommend to beginners who are learning for the first time. The lectures are kind and detailed, and you will be able to gain confidence in C language programming after completing the course. The lectures are somewhat long (about 4~5 credits for a semester of college), but you can learn from the basics to the application step by step. In my case, it took me about a month and a half to complete the course. This is a highly recommended course for those who are just starting to program.
