Human Biology Course I enrolled on the Human Biology Diploma course. This is my second course with them. I find this course to be very informative, with very good audio, visual and video presentations. I like the fact that there is a summary after each section and at the end there is a mock exam that allows an individual 3 attempts, which is good practice for the final exam. I also like that different presenters are used. In addition, the customer service is really good with very quick and helpful responses. I certainly highly recommend this course and perhaps trying them for other courses.
