Wondering if this study approach is a good idea

Sapphire

Im finding that Im having trouble passing quizzes (as in getting the results that i desire) at the end of a given section. Im really good at solving the questions correctly while practicing- as in pausing the video before JY explains it so that i can figure out the answer myself. But for some reason during the quiz section, Im not as good. To remedy this, I was wondering that as Ive completed each section, that I should use the practice exams to practice out those specific types of questions and to look at the video explanation for each of those questions. Would anyone suggest this? Has anyone tried this in the past? Please help!

Thanks.
