I'm not convinced of the quality of this course material. I thought I could try it out, see if I could fill some gaps in my knowledge. I tried out some of the quizzes and they were just bad. Course 1, week 2, for example, asks you to match items to where they go on a motherboard. This quiz is flatly wrong. It asks you to match a PSU to the rear Ethernet port, and a SATA cable to an IDE port. Being so obviously wrong about something so basic gives me serious concerns about everything else. I quickly cancelled the free trial.
