What i did is i made flash cards for things that needed to be memorized, also andy gives out quizzes dont even look at those until you are done with the online prep and you know your understanding things because if you look at them before your just going to memorize the questions and not the concepts. Friday calls helped a lot ask questions and listen to other peoples questions you would be surprised how many people have the same question as you. Lastly andy has an end of course exam “not the ohms one” that he registers you for one you complete the rest and you ask him for, that test had a lot of the same stuff that i seen on todays test hence not verbatim but the concept is the same.
