“I love the fact that these certification courses were given in "bite sized" sessions, that there were exercises and answers to download after each session, and you get multiple chances to pass their final exam. Then, they'll tell you the # right and wrong and what areas you need to study. They can't tell you the exact Q&A you got wrong, which is pretty normal. I also love that I can go and explore other courses that if I wanted more info on a particular area of this program. The session will tell you if they offer additional session if you want to learn more about a, b, and c. Well worth the money!”
