<p>I scored what (for me) was a disappointing 27 on the Math section of the April test. </p>
<p>Seeing as math is one of the more straightforward subject areas to bring up on the ACT test, compared to say the Reading, i'm looking to try and maximize my math score on the June test.</p>
<p>For those who have taken previous ACT tests and scored around the high end 33+ area: what specific formulas did you find it necessary to memorize for the ACT test(s)?</p>
<p>Quadratic formula is a must, distance formula helpful, the formulas for volume of solids helpful. Has the ACT Math ever had questions involving surface area of solids? Any others that would be necessary or help for questions that even -might- appear on the next ACT?</p>
<p>I didnt memorize anything nor study any of the ACT stuff. I just worked the problems and got a 35. Just pracitce and know what to ex[ect is all I can tell you. I think I did look at a formula once but for thing like volume it is always area base times height. Surface area I think like cube is 6 times the area of one side.
Know the concept and understand concepts over memorizing. If you know how they derive then your fine.</p>
<p>Hmm, I don't think it's always the same for volume, unless there's some easier way to derive it that I haven't recognized. Cones and spheres for instance are different. They are the typical area of base x height ... but for cones, it's multipled by 1/3. For spheres, multiplied by 4/3. Surface areas are a little different for certain figures too I believe.</p>
<p>I think the main benefit of formulas is that they speed things up a great deal. I know on the last test, my method for finding distance was drawing the line as a triangle against a coordinate graph and using pythagorean theorem. Knowing the distance formula would have saved me an easy minute on just that question alone.</p>
