<p>I'm taking Literature in October, and Chemistry and Biology in November. However, I'm homeschooled, and I haven't studied any of these subjects to the level a high-school student would. </p>
<p>I have these books: Barron Literature/Barron Chemistry/ Princeton Review Biology. Are these all I need to self-study for the tests this autumn, or are there any other books you would recommend? When should I start studying these subjects?</p>
<p>Thanks :).</p>
