<p>Again the wording of the qeustion seems vague and odd but anyway I'm studying the math section and have the Blue book second edition but there's this thing online where this guy explains all the problems in the Blue book's old edition, he makes videos that show how to solve all the math problems from the test in the old book. And I was just wondering if its okay to watch them, would they help me with the math section. I'm still going to use the BB second edition.</p>
