<p>My first tip: don’t take it freshman year. There’s no point in taking it this early. You will have enough time to take it junior year, after taking the SAT I. Plus, by the time you are a junior, you can take an AP bio course, which teaches you a lot of the stuff you need to know for the subject test. But if you really want to take it this year for some reason, I think your studying is a little overkill. The bio test isn’t really as difficult as you think. Most of those practice tests in the books you’re studying from are very unrealistic from the actual test. I’d recommend getting the collegeboard guide to all the SAT subject tests and do the practice test in that, because it is a real test and gives you an actual representation of what the test will be like.</p>
