<p>I'm homeschooled, and I don't know much of either Bio or Chem; I only know the absolute basics, if that, and I haven't taken any exams in the subjects. I'm applying to college this autumn. I have the Barron's Chemistry book and the Princeton Review Biology book, which people say cover both topics pretty well. My questions are:</p>
<p>-When should I start studying these if I want to do the Subject Tests in November/December? (I learn science subjects fairly quickly, and I'll be quite busy with other work up until July. Should I start then?)</p>
<p>-What do I have to learn beforehand? Which topics, etc? I've looked at my books and I should be able to start learning Chemistry immediately, but Biology requires a basic knowledge of organic chemistry. I'm not sure if anything else is required.</p>
<p>Any advice would be much appreciated. Thanks :).</p>
<p>I self-studied Biology and took it in January 2009 after completing Biology in June 2008. I had ALOT to learn because I was only in Regular Biology, but I studied consistently for like a month beforehand and did pretty well (like 70th percentile).</p>
<p>And you really don’t need to know jack about orgo for bio, except maybe how to recognize a few molecules. Or for example, what makes something an aldehyde instead of a ketone. But nothing overly in depth at all.</p>
<p>ketone and aldehyde ive never come across these terms in my honors biology class all i know is that there is a carboxyl and amino group, should i know whAT KETONE AND ALDEHYDE ARE?</p>
