How Long Is the HESI A2? Why There's No Single Number
Search for how long the HESI A2 takes and you will find answers from 50 minutes to six hours. None are quite wrong, because the exam is modular: your nursing program picks the sections, and that choice sets both the question count and the clock. Here is the section-by-section breakdown.

If you search online for the answer to the question “how long is HESI A2 exam”, you’ll quickly realize there are varied responses. Some sources will claim 50 questions for 50 minutes; others cite a range of 4 to 6 hours. None of them is exactly wrong, because the HESI A2 is modular rather than a fixed exam. Your nursing program is responsible for picking which sections you take, and that choice determines the question count and the total test time. This guide breaks down the section-by-section structure, explain why your school controls the clock, and show you how to find your actual exam length before test day.
How long is the HESI A2?
The answer is, it depends on which sections your nursing program requires. The test contains up to eight academic sections, and each section carries its own time limit and question count. Because schools choose which sections to require, the total length varies from one applicant to the next.
Here's the full section-by-section breakdown so you know what you're working with.
Section | No. of Questions | Time allowed |
|---|---|---|
Mathematics | 50 to 55 | ~50 minutes |
Reading Comprehension | 47 to 55 | ~60 minutes |
Vocabulary | 50 to 55 | ~50 minutes |
Grammar | 50 to 55 | ~50 minutes |
Biology | 25 to 30 | ~25 minutes |
Chemistry | 25 to 30 | ~25 minutes |
Anatomy & Physiology | 25 to 30 | ~25 minutes |
Physics | 25 to 30 | ~25 minutes |
If your program requires all eight sections, you could face roughly 300 to 340 questions across a little over five hours of testing — though very few programs require all eight. A more common four-section exam, covering only Math, Reading, Vocabulary, and Grammar, would land closer to 200 questions in about 210 minutes. Most students are given up to four hours total, though some programs allow more and others impose no strict time limit at all.
In short, the answer to how many questions are on the HESI A2 depends on how many sections your program ordered. The answer to how long is the HESI exam depends on the same factor.

Why your school decides
The HESI A2 is published by Elsevier, but Elsevier doesn't decide what you sit for. Each school that partners with Elsevier selects which sections its applicants must take and sets the minimum scores needed for each one.
That's why two students can say they took the HESI A2 and describe very different exams. One sat for four sections in a community college testing room. The other sat for seven sections at a Prometric center. Same name on the test, different experience entirely.
Programs that are focused on foundational academic readiness often test the four core sections: math, reading, vocabulary, and grammar. Programs that lean heavily on science prerequisites — competitive BSN programs in particular — tend to require biology, anatomy and physiology, and sometimes chemistry on top of the core four. The two approaches reflect what each program prioritizes in its applicant pool.
Score thresholds also vary by program and by section. Most ADN programs accept a composite score of around 75 to 80 percent. Competitive BSN programs often require 85 percent or higher, sometimes with minimum scores per section rather than just an overall composite. Anatomy and physiology is widely reported by applicants as the hardest section, so programs that require it are effectively raising the bar. Our nursing school requirements guide covers admissions expectations by program type, and our HESI A2 entrance exam overview explains how to work out which sections apply to you.

How to find your actual answer
Only your nursing program can tell you what your version of the HESI A2 looks like — Elsevier publishes the section catalogue, but your school decides which ones you sit. Five checks will get you the full picture before you register: the required section list, the timing format, the per-section score floors, the testing venue, and the retake policy. Work through them in that order.
Check the program's admissions page first. Most nursing programs list required entrance exams alongside GPA cutoffs and prerequisite courses. Look for a section called "admissions requirements" or "application checklist."
Call or email the nursing department directly. Admissions pages don't always reflect the most current requirements. A two-minute call to the department can confirm whether the section list has changed, what the time format is (per-section timers vs. one overall window), and whether the test is offered on campus or through an outside testing center.
Ask specifically about the timing format. Some programs give you 50 minutes for the math section and 60 for reading. Others give you a block of, say, three hours and let you move through the sections at your own pace. These formats call for different pacing strategies on test day, so knowing in advance matters.
Confirm the score requirement per section, not just the overall composite. Some programs publish a single composite cutoff. Others require a minimum score in each section individually. If there's a per-section floor on math or reading, you need to know that before you sit.
Find out the retake policy before you register. Most schools require a 60 to 90-day wait between attempts and cap retakes at two or three per admissions cycle. Having this knowledge upfront shapes how seriously you treat your first attempt.

In person or at home?
How long your exam feels also depends on where you take it. The HESI A2 is offered through three channels: at your school's own testing center, at a Prometric testing center, or online through remote proctoring. Each format has real differences worth knowing before you book.
Testing channel/ format | Description |
|---|---|
School testing center (On-campus) | Most common for programs that administer their own sessions. Schedule through the school directly. |
Dedicated testing facility (Prometric center) | Prometric offers both in-person and remote proctoring options. Book through Evolve/Elsevier. |
Your home or private location (Remote/online) | Requires webcam, mic, stable internet, and a private room. Some schools don't accept remote scores. |
While remote testing sounds convenient, it comes with conditions. Candidates will need a functioning webcam and microphone, a reliable broadband connection, a silent private room, and no notes, books, or papers within reach. A mirror is often required so the proctor can inspect your screen edges and desk. Some schools accept remote scores without question. Others, including several large BSN programs, strongly advise against remote testing or don't accept those scores at all.
Timing can also differ by format. Schools that administer the exam on campus sometimes use their own time windows. Prometric centers and remote sessions typically follow Elsevier's published per-section limits. If you're booking through Prometric, confirm whether your section list and time format match what your school expects. Not every program is set up identically within the Prometric system.
Before you book remote
Check whether your nursing program explicitly accepts remotely proctored HESI A2 scores. Some schools require in-person testing only. Others accept either format but flag technical issues during remote sessions as the student's responsibility, meaning a connection failure during your exam may count as an attempt.
The registration process runs through Evolve, Elsevier's platform. You'll create an Evolve account, pay the testing fee there, and then book your session through either your school's testing office or the Prometric portal. Fees vary. On-campus testing at schools that administer their own sessions is often lower, sometimes as little as \$45. Prometric in-person and remote sessions may carry additional proctoring fees. Confirm the cost at registration, not after — our guide to HESI exam cost explains why the price varies by school.
Frequently Asked Questions
How long is the HESI A2 exam?
It depends on your school's section requirements. Across all eight sections the published time limits total roughly five hours and ten minutes, but most students sit four to six sections and finish in two to four hours. Confirm your required sections with your program to get an accurate estimate.
How many questions are on the HESI A2?
The full HESI A2 has 326 questions across eight scored sections, plus 29 additional questions in two unscored profile modules. Your actual question count depends on which sections your program requires. The four core sections alone total 205 questions.
Does every nursing program require the same sections?
No. Each program selects the sections its applicants must complete. Most require the four core sections — math, reading comprehension, vocabulary, and grammar. Science sections like biology, anatomy and physiology, and chemistry are common additions at BSN programs. Physics is rarely required.
Can I take the HESI A2 at home?
Yes, if your program accepts remote scores. Remote testing is offered through Prometric's ProProctor platform and requires a webcam, microphone, stable internet, and a private room. Not all schools accept remotely proctored scores, so confirm your program's policy before booking.
What is the passing score for the HESI A2?
There's no universal passing score. Each nursing program sets its own cutoffs, typically between 75 and 80 percent for ADN programs and 85 percent or higher for competitive BSN programs. Some schools require minimum scores per section in addition to an overall composite. Check your program's specific requirements.
How many times can I retake the HESI A2?
Retake limits are set by your program, not by Elsevier. Most schools require a 60 to 90-day wait between attempts and allow two to three attempts per admissions cycle. Some programs require you to retake all sections. Others allow section-specific retakes. Get the retake policy in writing from your nursing department before your first attempt.
Is the HESI A2 harder than the TEAS?
Neither is objectively harder — they test similar content in different formats, and our TEAS vs HESI comparison covers the differences in detail. The TEAS has four fixed sections that all students take. The HESI A2 is modular, so difficulty depends partly on which sections your school requires. Students who are stronger in science may find the TEAS more challenging. Students who struggle with grammar or vocabulary as standalone sections may find the HESI trickier in those areas.
The Bottom line
How long is the HESI exam for you specifically? That question has one reliable answer: ask your nursing program. The full eight-section test runs a little over five hours by the published limits, but your version of it is shaped by the sections your school selects, the time format it uses, and the testing venue it accepts. Get the section list first. Then look up the per-section time windows, the score cutoffs your program requires, and the retake policy — in that order.
Once you have those four things confirmed, your prep plan and your test-day schedule both become a lot easier to build. For structured practice that matches the actual HESI A2 section format, the pre-nursing resources on Testavia are organized by section so your practice reflects exactly what you'll face.
