When should I take these SAT subject tests?

[mycollegelife]

<p>I planned to take the SAT subject tests for:
Chemistry
Math II
Biology</p>

<p>but when should I take them? To be more specifically, is there a class I should take to have the knowledge to get a high score on these subject tests? And what time of the year should I take them?</p>

<p>On the side note,
I am taking AP Chem, Pre-Cal HP, and some biology class that prepares me for AP Bio.</p>

<p>I took exactly the same tests as you and I took it in my junior year in june.
I used barron and princeton.
Since you are taking bio class for Ap Bio, SAT will be easier. Good luck!</p>

<p>You should take them in June right after your AP exam.</p>
