<p>My son took Honors Bio this past year. Based on his results on the Barron’s book practice test, he decided to take the E even though his HS course was much more oriented towards the M. A lot of the E stuff wasn’t even covered in his course, and he learned it exclusively from the review books (Barron’s and Princeton).</p>
<p>He basically covered all of the Barron’s book’s chapters and the most relevant (information intensive) chapters of the Princeton book in the three weeks before the test. Didn’t even look at the books before that. His Bio grades were a B first semester and an A second semester. He got an 800 on the Bio-E subject test.</p>
<p>There were a couple of things that we’d seen repeated here on CC in multiple threads that turned out to be true regarding the Barron’s book – that the practice tests get your attention by being difficult (with resulting low scores), but that you’ll do better on the real test. Also, if you know everything in the Barron’s book you’ll do extremely well.</p>
<p>I think it’s a bit crazy to be studying this far in advance for the test. However, my son said that the his studying for the subject test was the reason he got a high A on the second semester Bio final – his highest test grade of the year in that course. So studying now will probably help you with the course.</p>
<p>Hope that helps.</p>
