<p>I was wondering how many hours it takes to increase a score of 1600 to 1900. (Assuming that a person studies a lot and is reviewing the questions properly) Is one month, about 5 hours a day enough time? I think 9 more practice tests will be enough what are your comments/ thoughts/suggestions? </p>
<p>And what are your methods of studying/reviewing practice tests?</p>
<p>It depends on so many factors that it is impossible to say. If your 1600 was taken cold, without any prep or familiarity with the test, then bumping your score up will be a lot easier than if the 1600 was the result of extensive study. It will also depend on how effective your study is. Five hours a day is a lot; most people can’t focus that long.</p>
<p>The general consensus is that taking lots of TIMED practice tests, and carefully deconstructing the logic for why you got answers right and wrong is the best way to study.</p>
