i never read the book. i watched the videos once which in hindsight was prolly a waste of time. there are free study guides that people post that have vocab and random stuff that i read. bu tthe most added value was taking mocks. i just mocked until i dropped. and redid them over and over and over and over. i didnt even time myself most of the time. and i preferred readin the answer after every question as oppose to doing all the questions first then grading it. like sometimes i just answered b on everything so i can print out the exam with the answers and explanations.
