SAT Subject Test - Math 2 Portion help! :)

<p>Hi all,
I'm writing the SAT 2 (math2) subject test in May and I am practicing from the Barron's book. I know this book is supposed to be much harder than the actual test, and So I was wondering how much of trigonometry we need to know for the official SAT subject test - math 2.
Thanks for the help!</p>

<p>College Board says trig will be 12-16% of the test, but I can’t speak from any experience.</p>
