SAT2 Biology E/M; barrons-sat- bio book..?

<p>So i have barrons sat subject test bio e/m book, and i intend to take Bio-M, so do i have to go through the whole book, still? Or is it like i can still leave some topics which consist of Bio-E?
Is there any shortcuts? </p>

<p>And, what is general scoring curve for SAT bio??</p>

<p>Also, what is the ideal time of preparation( in days/ months) for a student who took bio in grade 12 ?
(ps i am an international ) </p>

<p>Thanks!</p>

<p>yes read the whole book imo…but you can scip some useless topics which never apear on the test. And the time to prepare depends on how much you still have in your brain,you can prepare for 1week or 2 weeks or 1 months,but for me I would be over prepared rather than not being well prepared,so I would say 1 month or atleast 3week.</p>
