Rusty at Math? GOOD. Now You Know What to Train

Say you run a team, sign off on budgets and haven't solved for x since college. You open your first Executive Assessment Quant question, see a percent and a fraction in the same sentence, and your stomach drops. Then comes the line I hear all the time: "I haven't done math in fifteen years." Said like a confession. Said like a verdict on your future.
Here is MY verdict: being rusty is GOOD news. Not "fine." Not "something you can work around." GOOD. Rusty is not the same as clueless. Rusty means you learned this stuff once, the parts are still in the garage, and now you get to find out EXACTLY which ones need oil.
The test is smaller than your fear
Start with what you are actually facing. The Executive Assessment (the EA) is a 90 minute test made by GMAC, the group behind the GMAT, and it was built for Executive MBA programs. It has three sections of 30 minutes each: Integrated Reasoning with 12 questions, Verbal Reasoning with 14, and Quantitative Reasoning with 14. You can see the full layout on GMAC's EA structure and scoring page.
Each section is scored from 0 to 20, and your total runs from 100 to 200. All three sections count the SAME. So Quant is one third of your score. Important, yes. The whole story, no.
Quant has two question types. Problem Solving is regular multiple choice: a question and five answers. Data Sufficiency is the odd one. You get a question and two facts, called statements, and you decide whether you have ENOUGH information to answer. You usually don't have to find the answer at all.
The test is also adaptive section by section. That means how you do on the first part of a section helps decide how hard the next part will be.
Now stop and think about this before you read another word. Fourteen questions. How many brand new ideas do you honestly think a test writer can cram into fourteen questions?
Not many. The same small group shows up over and over: fractions, percents, ratios, averages, number properties like odd and even, and simple equations. That is not a mountain. That is a short list, and a short list can be trained.

Why rusty can BEAT "good at math"
Here's the part people don't expect. The person who aced calculus often has a harder time on this test than the person who forgot it. Why? Because the math whiz reaches for long algebra on every question, and long algebra is slow. This is not a math test. It is a thinking test that uses math as the measuring stick.
You don't have old habits to break. You get to rebuild the RIGHT way from day one: write things down, try real numbers, and when the question gives you answer choices, use them. If you want the full version of that last move, read TEST THE ANSWERS Before You Touch the Algebra.
Let's see it in action.
No formula. No x. Just one answer choice and two lines of arithmetic you could do in grade school. That is what rusty people need to see early: the tools are SIMPLE.
The 5 mistakes rusty test takers make
Starting with a math textbook from chapter one. You re-learn things you never needed and burn three weeks before you touch a real question.
INSTEAD: Take one timed Quant section first. Let the misses tell you what to rebuild. Your rust is a map. Use it.
Doing the math in your head because "it's easy." It IS easy. That's exactly why the little slip hurts so much. Running a company doesn't make you immune to dropping a negative sign.
INSTEAD: Write every step on paper. Every time. In practice, so it's automatic on test day.
Calling every miss "I'm bad at math." That's not a reason. That's a mood.
INSTEAD: Name the cause. Forgot a rule? Misread the question? Arithmetic slip? Took the long route? Each one has a different fix.
Grinding through hundreds of new questions. Being an acquaintance of a thousand questions beats nothing. Being the master of two hundred beats everything.
INSTEAD: Redo the questions you missed until you can solve them fast, clean and the cheap way.
Panicking about the clock. Thirty minutes for fourteen questions works out to a little over 2 minutes each, on average. Average. Some take 40 seconds. Some take 3 minutes. If you're running out of time, the clock isn't the disease. Re-reading, head math and the long route are.
INSTEAD: Fix the cause and the pace follows.

So what do you want MORE?
You have a choice. You can keep saying "I haven't done math since college" like it's a life sentence. Or you can treat it like what it actually is: a clear list of things to train. You can't have both. The first one feels safer. The second one gets you into the program.
I'll bet that when you actually look at your misses, the list is SHORTER than you fear. Most of it will be two or three ideas that keep showing up, plus a handful of silly mistakes. Your score is earned, and this test is predictable enough that you can train for every piece of it.
Your challenge for today
Set a timer for 30 minutes. Do 14 practice Quant questions, a mix of Problem Solving and Data Sufficiency, with a pen and paper next to you. Write down your work for every single one.
When the timer stops, go back to each miss and write ONE line: what caused it. Not "hard question." A real cause. Then circle the cause that shows up most.
That circle is your first thing to rebuild. Start on it tonight.
