<p>The test really isn't something you can study for... it tests general science knowledge and the math section is basic algebra and arithmetic. The "challenge" section is 20 questions that range in difficulty, with none of them covering anything more than precalc.</p>
<p>I think the test they administer is just to verify your transcript and teacher recommendations, which are probably weighed more heavily.</p>
<p>As for statement of interest, I actually forgot to do that part when I was applying...I guess I misread that part. Regardless, I still got in.</p>
