<p>Well I have barron's and PR's math II and I'm also taking chem and spanish subject tests, along with math II. Chem and Spanish I'm not worried about, but I was wondering if it would be smart to supplement my Barron's and PR's with the collegeboard's math II book and also their big book of subject tests?</p>
<p>My pre-cal teacher is... incompetent to say the least.</p>
<p>The IIC book standalone is a waste of money. The same practice test appears in the complete version. You should get the complete version, so you can take a look at the other exams as well (and boost your confidence in Chemistry and Spanish)</p>
<p>well I ordered both but oh well =P</p>
<p>The Collegeboard Math book alone is not a waste because it includes two tests, while the Collegeboard book for all Subject Tests only includes one.</p>
