<p>So I took a previously administered PSAT (only the math section) and UNTIMED 2 days ago,<br>
and I got the last 3 wrong on the first section. And on the second section I got one multiple choice wrong, and the last 2 grid-ins wrong. So, my scaled score was a 64. I want to get a 70+. I have until October 12 to study, and my goal is to get a 215+. What can I do, and can anyone give me tips for the last math questions.
I have been studying for math by using the Powerscore database and am going through all of the arithmetic, geometry, algebra, algebra2...etc. problems that are in the BB...Im hoping that will really help...but other than that I don't know what to do. Please help! I really need that 215+!!</p>
<p>Same here. I constantly get 68 and never reached the 70s…
Bump this thread</p>
<p>Do you know what type of questions get you? Algebra II questions involving parabolas? Permutations/combinations? Geometric probability?</p>
<p>^ well, I’m able to tell what type of questions they are when i look at the powerscore database for BB, and then I just do those types of questions in the BB.</p>
<p>Also, from the questions I get wrong, I get most of the Geometry questions wrong. Especially the cubes and those 3 dimensional triangles and stuff like that. I also get those multi-step word problems wrong sometimes.</p>
<p>Cube problems are only going to test a few concepts:</p>
<ol>
<li><p>Volume
They’ll rarely ask for the volume. Instead, you’ll be given the volume and asked to solve for the length, width, or height. Or, the l, w, h will be needed to determine the area/volume of a connected figure.</p></li>
<li><p>Surface area
Surface area problems usually have two or more cubes stacked on top of each other and you have to subtract the area of the non-exposed sides.</p></li>
<li><p>Distances from vertices
The farthest distance from a single vertex is its diagonal vertex. </p></li>
<li><p>The length of a diagonal
This is for questions like "What’s the longest pencil that can fit in a cube with a side length of 4? This takes finding the lengths of two right triangles.</p></li>
</ol>
<p>If you learn how to tackle all of these situations, you’ll be ready for any cube or rectangular solid question.</p>
