<p>Different strokes for different folks.</p>
<p>Arguing over whether or not test prep is worth it in general isn't going to lead to any mind-shattering conclusions. Many people have done well with self-study, and others need the tutoring to help them focus and learn the relevant information.</p>
<p>I self-studied for the SAT's and was basically obsessed with them for a few months. I devoured multiple tests and books until I felt I had completely mastered the material. By focusing on weaknesses and fine-tuning my strengths, it was easier to see the patterns to the questions in the tests and give the best answers after knowing what they were looking for. Eventually I ended up with a 2390 (old SAT 1590 + SAT2 Writing 800).</p>
<p>I taught the SAT to a bunch of kids as an official tutor during my sophomore year here at Penn. I can tell you right now, most of those kids did not want to be there. The other kids who were genuinely trying to do better did so by a much larger margin than the unmotivated kids who didn't give a rat's ass about the SAT. The unmotivated kids were there because their parents pretty much forced them to.</p>
<p>However, those motivated kids would have probably done well anyway without the tutoring, but to what extent is the question. Sometimes a motivated student can do well on their own, but they may desire additional help to ensure that their focus is in the right direction. What better way to learn the test that to take advice from someone who's already been through the process and knows all the little hidden tips and tricks and optimal strategies? </p>
<p>Instead of spending all that time trying to discover these tricks for yourself, it is sometimes easier to just pay someone to tell you what to look for. Tutoring has its merits, and while I don't tutor anymore, I don't discourage people from seeking test prep if they feel it would really benefit them. It's like paying for piano lessons. You could spend hours figuring out the optimal finger positions and chord structures and so forth, practicing music at your own pace, but odds are you'll do better if you're motivated and you learn from a pianist who knows the ropes and can tell you how to improve yourself more quickly after developing the right approach. On average, what kind of people are going to be able to pull off the Third Movement of Moonlight Sonata? The people who taught themselves piano, or the ones who learned from others with experience? Test prep is no different -- sometimes people just need the help.</p>
<p>Yes, it is true that people from well-off families still do poorly on the SAT even with prep. All money does is provide the resources. It doesn't buy intelligence or a genuine motivation to succeed. However, test prep won't HURT you, and this is why people who enroll in test prep usually have, on average, higher scores. It is this sort of concept that drives the correlation between wealth and academic performance.</p>
