<p>I improved my ACT score by 4 points in 6 hours. Here how I did it:</p>
<p>1) I had already taken the PLAN test and got a 27: (30 English, 30 Reading, 28 Math, 21 Science). That predicts about a 30 ACT.</p>
<p>2) I decided to focus first on science. I bought a Princeton Review book and read all their strategies thoroughly. I went through all their mini-quizzes slowly and analyzed the results. I was able to narrow my focus down to the specific types of problems I was having trouble with, and then master those problems.</p>
<p>3) I then took an untimed practice test just for science, and went over all my wrong answers. I made sure I knew the reasoning behind the correct answer to every single one. I retook that test and got all of them right (no, I had not memorized the answers).</p>
<p>4) Then I went onto math. I just went through the concepts that looked tough, took a practice test, and went over the answers and made sure I understood them. Then I took a different practice test.</p>
<p>The next day, I took the ACT. I got a 34 (36 English, 35 Reading, 34 Math, 30 Science).</p>
<p>Could I have gotten a 35 by preparing diligently for months? Maybe. But just one day of cramming yielded almost the same result. By limiting my total study time to 6 hours, I was able to stay alert and efficient. But most importantly, I was forced to focus on what was the most important instead of trying to be comprehensive, thereby wasting my time on information I had already mastered.</p>
<p>Obviously you will not have the same strengths/weaknesses that I had, and your study plan will probably be nothing like mine. I just wanted to share an example of how just a moderate amount of deliberate, focused prep can be extremely effective.</p>
<p>So I guess my answer to your question is: you don't need to devote massive amounts of time to get a great score. You may need to in order to get an amazing score. Otherwise, just a few days of diligent study could make a tremendous difference.</p>
