Ap Bio and Us History cram

Did anyone here use only the review book for the apush or ap bio and got at least a 4 on the exam?
For the people that got a 4 or 5 do you feel its absolutely necessary to use the textbook in order to do well? And if you just use the textbook then do you also take notes while reading or just skim it to try to memorize details.

Also do you guys think watching review videos on you tube is worth the time? Im trying to cram for both exams in less than a month pls help looking for suggestions,inspiration, effective study plans , advice ,etc
