<p>after taking 27 tests, will pretty much anyone be as high as they’re going to get (hopefully at 2400, maybe not)</p>
<p>what do you think?</p>

<p>It doesn’t really matter how many tests you take as much as how you prepare for them. If you don’t double check, review every problem, and focus on your weaknesses, you can either go 100 tests without seeing improvement. But if you prepare the right way, in just 2-3 tests you can see a big improvement.</p>
<p>I agree with the pst that Borid put up. It states that the more you consume of a certain good or service the less you get out of it. So if you take more and more tests, you should not expect to get the same marginal benefit as you would when you take your first couple of practice tests. I think that after a while your marginal utility becomes negative if you took too many tests, and that causes your total unitility to go down.</p>
