Crammer's rule

<p>how much depth do we need to know on the exam and do we need to know crammers rule and other hard stuff???</p>

<p>for math II C
in Barron </p>

<p>and is there any use to taking the exams in Barrons is it a waste and the questions will be a lot easier</p>

<p>crammers is pretty easy. all that polar stuff is hard. i’m prepping from barron’s. atleast i know i can always expect MORE than i get on the practice tests rather than the other way round.;-)</p>
