</ul>
<h4><b>Polishing Your GRE Math Skills</b></h4>
<p><span style="font-weight: 400;">Memorizing math rules and mastering problem-solving strategies are starting points for GRE Math. However, even if two people know exactly the same list of math techniques, they can end up with very different GRE Math scores. The difference lies in what the GRE is </span><i><span style="font-weight: 400;">really</span></i><span style="font-weight: 400;"> testing: executive reasoning skills.</span></p>
<p><span style="font-weight: 400;">“Executive reasoning” refers to the type of high-level thinking you use when you have to make tough decisions, quickly, with limited time and information. You’ll need to do that, over and over again, as you take the GRE! You don’t get to spend all the time you’d like on every GRE Math problem. You also don’t get to test out multiple approaches to each problem until you find the perfect one. You need to set priorities and make the strategic moves that will maximize your score—even though that sometimes means guessing on ones you might be able to get right.</span></p>
<p><span style="font-weight: 400;">Don’t think that memorizing math rules is the main goal of your GRE Math studies. You should also spend plenty of time doing problems. And when you do problems, at least some of the time, do them in </span><b>timed, random sets</b><span style="font-weight: 400;"> and </span><b>use a timer while you practice</b><span style="font-weight: 400;">. Also, when you fill out your </span><a id="bloglink" href="https://www.manhattanprep.com/gre/blog/gre-problem-log-quant/" target="_blank" rel="noopener"><span style="font-weight: 400;">problem log</span></a><span style="font-weight: 400;">, review problems that you spent too much time on, or where you picked an inefficient approach, even if you got them right in the end. </span></p>
<p><span style="font-weight: 400;">There are other GRE Math skills, too. One GRE Math skill is your ability to handle test anxiety and mental fatigue. GRE Math experts are those who improve their test-taking stamina ahead of time so that they won’t get worn out on test day. They also address test anxiety head-on, rather than ignoring it and hoping that it goes away! Check out our </span><a id="bloglink" href="https://www.manhattanprep.com/gre/blog/managing-gre-anxiety-before-test-day/" target="_blank" rel="noopener"><span style="font-weight: 400;">GRE anxiety reduction tips</span></a><span style="font-weight: 400;"> for some ways to do this yourself. The GRE Math section also tests focus: can you pay careful attention to every single problem and avoid missing details and making careless mistakes? Luckily, </span><a id="bloglink" href="https://www.manhattanprep.com/gre/blog/your-attention-please/" target="_blank" rel="noopener"><span style="font-weight: 400;">focus can be trained</span></a><span style="font-weight: 400;">, and there are many ways to </span><a id="bloglink" href="https://www.manhattanprep.com/gre/blog/careless-gre-math-mistakes/" target="_blank" rel="noopener"><span style="font-weight: 400;">avoid careless errors on test day</span></a><span style="font-weight: 400;">. </span></p>
<p><span style="font-weight: 400;">You might not need geometry and inequalities in graduate school or in your career. However, you’ll definitely need some of the core GRE Math skills: executive reasoning, decision-making, focus, attention, and the ability to stay relaxed under pressure. Studying GRE Math is a unique chance to push yourself, grow, and hone your skills. ?</span></p>
