<p>Regarding perfect scores, it is true that some individuals will reliably score at the 2400-mark. However, it is very difficult to consistently score at that level without some sort of cognitive adaptation. That is, it is critical to have some sort of initial familiarization with the format of the test and knowledge of all relevant expectations. I began studying for the SAT this past September, but it took two months, eight complete practice tests (twelve Math sections), and two official takings until I truly felt that I had the self-confidence and experience with the test to repeatedly score at the 2400-level (which I eventually achieved at the December 5th administration). I believe that this may have been fully attributed to the fact that I simply had not been exposed to the test for a large period of time and had not had enough cumulative practice at the instances of my first two takings. Consequently, I had two scores in the mid-2300s (two practice tests after the first, four after the second).</p>
<p>So the basic implication of my own personal experience is that a complete familiarization with the SAT (or any assessment) is absolutely vital before one is truly able to maximize his or her performance.</p>
