The way the VMEdu courses are as follows, you can purchase them from us at a discount, and we will send you a code to start the courses via VMEdu website, which you can access by clicking the logo above or on "Our Friends."  We can offer a discount as they sell to us at a discount, and we help spread their services, so good all around.  Having taken some of the courses, and this is a free demo course, we would describe them as complete in the knowledge set, not easy but not hard; in other words, you need to pay some attention.  There is an exam at the end of each course which was fairly built, with no trick questions, and you will receive a certification of completion after you pass.
