Getting Through the Chamberlain Hesi A2 Exam Without Losing Your Mind
The Chamberlain Hesi A2 Exam is a requirement for their nursing program admissions. It covers reading, vocabulary, grammar, math, biology, A&P, chemistry, and general science. Chamberlain typically wants a composite score of 75 or higher, though some terms might request individual section minimums. The exam is proctored through an online platform, and you get about 14 hours total to complete it. You can take it once every six months. The exam isn't a single monolithic test. It's a collection of subtests, and you register for the ones Chamberlain requires. Reading Comprehension has 52 questions. Vocabulary and Verbal Expression together account for about 80 questions. The math section is 55 questions covering arithmetic, algebra, and word problems. Biology is 58 questions. Anatomy and Physiology is the longest section with 93 questions. Chemistry has 47 questions, and General Science adds 52 more. The questions are multiple choice only. Most people underestimate the A&P section. It's nearly 40% of the entire exam in question count alone. I took this exam in 2021 and spent roughly two weeks prepping. The bulk of that time went into A&P and anatomy. The general knowledge sections like chemistry and general science can be reviewed quickly if you have a recent college-level background in them.
How to Prepare for It
You need a study guide that mirrors the exam structure. The official HESI A2 study materials from Elsevier are the standard reference. Many programs sell these through their school bookstore or directly on the HESI website. There are also third-party prep books, but I'd stick with the Elsevier one because the question style matches what shows up on the actual test. The third-party versions tend to have slightly different wording and difficulty distribution. For the math section, you need to be comfortable with fractions, decimals, percentages, ratios, and basic algebra. I kept a small notebook of fraction-to-decimal-to-percent conversions. It sounds elementary, but I caught myself second-guessing 3/8 as a percent during practice. That kind of hesitation costs you time, and you don't have time to waste on a section where you're given roughly one minute per question on average. The reading comprehension questions come in passages with five questions each. Practice with long passages. The HESI passages are dense, sometimes two paragraphs or more, and the questions test inference as much as direct recall. I found it helpful to read a medical journal article or two daily just to build stamina for processing complicated text under time pressure. Not medical topics specifically, just any dense prose. The goal is to train your brain to not zone out after paragraph two.
Registration and Scheduling
You register through the Elsevier HESI portal, not through Chamberlain directly. Chamberlain gives you instructions in their admission packet, but the actual booking is done on the HESI side. You select "Academic" as the exam type, choose the subtests you need, and pick a testing window. The proctoring is remote through an AI monitoring system. They track your eye movement, require a clear desk, and will flag anything that looks like you're looking away from the screen repeatedly. There's a $60 fee per subtest when you book through HESI directly. Chamberlain sometimes has a partner discount that brings it down, so check your admission packet or email for a promo code before paying. I used one that cut the A&P section fee in half, which mattered because that section alone is expensive to take standalone.

What Actually Happens During the Exam
The interface is straightforward. One question at a time, with a timer visible in the corner. You can skip questions and return to them later within the same section, but the overall exam timer keeps running across all sections. This matters because people sometimes finish reading quickly and then burn through their remaining time on the A&P section without realizing the clock hasn't stopped. I hit a specific issue during my own exam that I wish someone had warned me about. The math section has a built-in calculator tool, but it only works for certain types of problems. When I tried using it for a unit conversion question involving dimensional analysis, the calculator interface froze mid-calculation. I had to switch to manual computation, which I wasn't set up for on the fly. The workaround was simple: skip the question, keep going, and come back if time allowed. I didn't come back, and I got it wrong, but it cost me maybe two minutes of stress instead of ten. Flagging questions as skipped rather than staring at a broken tool is the actual move here.
Pitfalls to Avoid
The biggest mistake I see people make is treating the exam like a knowledge test rather than a pacing test. You are expected to answer most questions. Leaving blanks is worse than guessing, because there's no penalty for wrong answers. On the reading section especially, people spend four minutes on one passage and then rush through three more. The four-minute passage gets you two wrong answers anyway because you're exhausted from overthinking it. Another issue is the vocabulary section. It includes medical terminology mixed with general academic vocabulary. Words like "proclivity" and "belligerent" show up alongside "hemostasis" and " Homeostasis." If your foundation in medical terminology is weak, focus on prefixes, suffixes, and roots. Knowing that "hepat-" means liver and "-itis" means inflammation gets you halfway to the answer without needing to know the exact definition of the word in front of you. This trick comes up on almost every section, not just vocabulary. The grammar portion tests comma usage, subject-verb agreement, pronoun agreement, and sentence structure. It's not heavily weighted, but it's easy points if you already know the rules. I reviewed a single page of comma rules and got nearly all of those questions right. Don't skip that section entirely thinking it doesn't matter.
Score Release and Retakes
Scores are released within a few business days to both you and Chamberlain. The composite score is what they care about most. Individual section scores below 70 can sometimes trigger a conditional admission review, even if your composite is above 75. I've seen students with a 78 composite get put on review because their A&P score was 64. Chamberlain's policy changes occasionally, so verify the current minimums on their admissions page before you sit for the exam. If you don't hit your target, you have to wait six months before retaking. That's a hard rule, not a suggestion. The six-month window applies to the entire exam, not individual sections. You can't retake just the math portion and wait six months for that one. It's all or nothing on the retake timeline. The Chamberlain Hesi A2 Exam is manageable if you prepare for the format, not just the content. The pacing, the interface quirks, and the section distribution are as important as knowing your Krebs cycle. Focus your study time on the sections that carry the most weight and that you're weakest in. Everything else is incremental gains.
