<p>Hey all,</p>
<p>During this coming summer I wanted to prep in AP Biology, AP physics I, and AP European History.</p>
<p>I’ve only started preparing for AP Bio, and am unsure how much I should prep. For example, do you think that I should memorize all of the enzymes in glycolysis or just know the basics of respiration?</p>
<p>With all of the AP tests, should I:</p>
<p>1) Learn the textbook or the practice book?
2) Learn the concepts or do the problems or both?
3) Take the practice tests?</p>
<p>Thanks!</p>
