Took several courses over the years, instructors were knowledgeable and had real world experience. Apparently instructors are now outsourced and the lowest bid wins. The course I just took had an instructor who admitted that. When a company charges me a premium rate for a course but uses the lowest paid East Asian workers to deliver, that gets ridiculous. I would suggest that anyone planning to take a course ask who the instructor is and what is his/her experience and expertise before paying a dime. For myself and my organization, we are done with Global Knowledge.
