“I found the online lectures and printout PowerPoints were very helpful.  I was able to pause, rewind and rewatch the lectures as I needed to take notes and make myself flash cards.  The lectures broke down the things I couldn’t teach myself such as physics and getting the resolutions straight in my head.  I passed with an 87!”
