<p>I am currently a senior. These are the tests I have already taken:</p>
<p>Junior year:
US History- 760</p>
<p>Sophomore year:
Math Level 2- 740
Chemistry- 700</p>
<p>Freshman year:
World History- 680</p>
<p>I am considering retaking math and taking the biology E or M subject test in November. </p>
<p>2 questions:</p>
<ol>
<li><p>I think I can get an 800 in math if I study enough for it, but is it worth my time trying to raise my score?</p></li>
<li><p>I haven't had biology since freshman year and this year I am going to take IB Biology HL. Is it possible to self-study for the bio subject test in only a month? I'm taking the SAT in October so I'm focusing on that right now and if I take subject tests it will be in November. </p></li>
</ol>
<p>I am looking into schools like Stanford and UC Berkeley for environmental science. I got a 2060 on the SAT (800 math, 610 reading, 650 writing) but will retake to get them all in the 700's.</p>
