Getting Through the Math Section on the Hesi A2
The math portion of the HESI A2 isn't brutal if you've actually dealt with fractions in real life. But a lot of people get tripped up on questions that look straightforward until they try to solve them under a timer. I've watched students lose points on things they could do in their sleep when they had no time pressure. One thing nobody tells you about this test: the question format is intentionally messy. They'll give you word problems where the numbers are scattered across two or three sentences, and the operation you need to perform isn't obvious until you actually translate the sentence into an equation. I spent too many minutes on one particular problem once where they asked about mixing two solutions at different concentrations, and I almost overthought it into picking the wrong operation. The trick was just writing out what the question literally says before doing anything else.
Hesi A2 Practice Test Math: What You Actually Need to Know
Here's the breakdown of what shows up most frequently and what the questions are actually testing. This isn't a comprehensive math curriculum review. It's the specific territory the exam covers. Arithmetic and fractions dominate. I'm talking adding and subtracting fractions with different denominators, converting between mixed numbers and improper fractions, multiplying and dividing fractions including those messy word problems with fractions of fractions. Then there's decimals and percentages. Converting 0.375 to a fraction, calculating what percentage one number is of another, finding the percent increase or decrease between two values. These show up constantly. Algebra basics come in next. Solving one-step and two-step equations, working with exponents and square roots, understanding order of operations when things get intentionally complicated, and basic inequalities. The algebra questions are usually simpler than what you'd see on a placement exam for a college algebra course, but they're worded in ways that make them feel harder than they are.
Geometry is lighter but still present. Area and perimeter of rectangles, triangles, and circles. Volume of rectangular prisms and cylinders. The circumference and area formulas for circles come up more often than volume. They expect you to memorize pi to at least two decimal places, usually 3.14. Number theory rounds it out. Prime factorization, greatest common factor, least common multiple, distinguishing prime from composite numbers, working with integers including negative numbers in operations. The integer questions are where a surprising number of students make careless errors, especially when subtracting a negative or multiplying two negatives.

How I Approach Practice Without Going Crazy
My recommendation for practice isn't to take ten full tests. It's to do targeted practice on your weakest areas until they stop being weak. I found that doing broad practice without tracking which question types I missed was basically a waste of time. You end up reinforcing what you already know and ignoring the stuff that actually costs you points. When I was prepping for this, I pulled together about 50 practice problems focused specifically on fraction operations and percent calculations. Those two topics alone made up maybe 40 percent of the math section. I worked through them untimed first, then did a second set under actual test conditions with a 45-minute timer since that's roughly the pace you need for the real thing. There are a handful of free practice resources online. The official Elsevier/HESI site has some sample questions. Beyond that, a few nursing prep websites offer free practice tests with answer explanations. The ones with explanations matter way more than the ones without. If you're just clicking through and checking right or wrong without understanding why you got something wrong, you're not actually improving.
What the Free Practice Tests Get Wrong
I need to be honest about a limitation here. Most of the free Hesi A2 practice math tests online don't match the actual difficulty or question style very closely. Some of them are too easy, which gives you a false sense of confidence. Others are oddly formatted in ways that don't reflect how the real test presents information. The ones that are closest tend to be behind a paywall on sites like Kaplan or various nursing prep platforms. Also, the free tests often skip certain topic areas entirely. You might finish a 25-question practice test and realize none of them covered integer operations or geometry. That doesn't mean those topics won't be on your actual exam. It means the practice resource is incomplete. If you're serious about this, I'd suggest combining whatever free material you can find with a dedicated math review book aimed at nursing entrance exams. The book will give you systematic coverage of every topic area with progressively harder practice problems. That's where I got most of my actual improvement from.
Common Pitfalls I See Repeat Themselves
Students consistently mess up the same three things. First, they forget to find a common denominator before adding or subtracting fractions. They'll just add the numerators and add the denominators, which is wrong every single time. Second, they flip the percent calculation backwards when asked "what percent is X of Y." The setup should always be part divided by whole times 100. Third, they panic on word problems and skip them entirely, which costs them easy points because half the time the problem is just a translation exercise. Another thing that catches people off guard: the test uses a basic on-screen calculator for some sections but not others. When the calculator is available, make sure you actually know how to use it efficiently. Don't waste time trying to type in complex fraction expressions when converting to decimals first would be faster. When the calculator isn't available, you need to do mental math or scratch work, so practice both modes. The timing is tight. You're looking at roughly one minute per question on average. That means if you get stuck on a problem for more than 90 seconds, you should guess and move on. Coming back to hard questions eats into the time you need for the easier ones at the end, and those are the points you're guaranteed to get if you stay calm.

Bottom Line
The Hesi A2 math section is passable with focused preparation. It tests foundational math skills, not advanced problem solving. The people who fail it usually didn't study the right material or they let the timer create panic decisions. Do targeted practice on your weak spots, understand why you're getting answers wrong instead of just noting the right answer, and manage your time so you never leave easy questions undone. That's really all it takes.
