How the ACLS exam works, and how to pass it

The ACLS exam is three checks, not one test: the precourse self-assessment, the skills tests (including the Megacode) and the written exam. The hands-on side is a high-quality BLS (adult CPR and AED) skills test, an airway management skills test and the Megacode; the written part checks the same algorithms on paper. Nerves about the Megacode are normal, and it is the part that practice changes fastest.

3 parts

What the ACLS exam is made of

Every path through the AHA Advanced Cardiovascular Life Support (ACLS) Provider Course ends in the same three checks, whether you sit in a classroom for the whole course or do the online part at home first. They test different things, so they need different practice.

The parts of the ACLS exam
PartWhat happensWhat passing looks like
Precourse self-assessmentAn online Precourse Self-Assessment that every student completes before class; its sections are rhythm recognition, pharmacology and practical application.A score of 70%; you can retake it until you reach the line.
BLS skills testAdult CPR and AED use on a manikin, with feedback on rate, depth and recoil.The right rate and depth, little hands-off time, a shock delivered safely.
Airway skills testOpening the airway, an adjunct, bag-mask ventilation.A sealed mask, visible chest rise, no over-ventilation.
MegacodeThe Megacode, a simulated case in which you act as team leader; the rhythm changes as you go.The right algorithm for each rhythm, said out loud as clear orders.
Written examMultiple-choice questions built on cases, rhythms and drugs.84%, the figure Training Centers usually quote (your instructor confirms the exact rule).

Each part has its own practice here: the precourse practice for the self-assessment, the CPR and airway cards for the first two skills tests, Megacode practice cases for the team-leader test, and the 60-card practice test for the written exam.

Written

The written ACLS test

Yes, there is a written ACLS test. Expect usually about 50 multiple-choice questions (as AHA Training Centers report it; confirm the count with yours). It is open resource at most Training Centers, so the provider manual and your notes are usually allowed, which sounds generous until you notice that almost every question is a short case: a rhythm, a blood pressure, a symptom, and four plausible next steps.

What the questions lean on

The AHA does not publish topic weights for the ACLS exam, so any split you see online is an estimate, ours included. The heavy areas are easy to name, though: the cardiac arrest algorithm with its shock-or-no-shock branch, bradycardia and tachycardia with a pulse, the reversible causes (the H’s and T’s), high-quality CPR, post-arrest care, and the first minutes of acute coronary syndromes and stroke.

Our estimate of where the written exam's questions sit
  • Cardiac Arrest: VF/pVT, PEA & Asystole20% · 12 cards
  • Bradycardia & Tachycardia with a Pulse18% · 11 cards
  • High-Quality CPR, BLS Survey & Airway17% · 10 cards
  • Acute Coronary Syndromes & Stroke14% · 8 cards
  • Rhythm Recognition & ACLS Pharmacology12% · 7 cards
  • Post-Cardiac Arrest Care10% · 6 cards
  • Team Dynamics & Systems of Care9% · 6 cards

Estimate, not an AHA number: the AHA does not publish topic weights for the ACLS exam. We weighted the topics by how the course cases are built and by the topic split of 1,447 app questions; the practice test samples its 60 cards the same way.

Skills

The ACLS skills tests and the Megacode

People search for the “ACLS practical exam” more than the written one, and with reason: it is the part you cannot cram. The skills side is a high-quality BLS (adult CPR and AED) skills test, an airway management skills test and the Megacode. The first two are short. The Megacode is where nerves show, because you speak the algorithm instead of choosing it.

  1. 01High-quality CPR and the AED

    The manikin reports what you do. Push at 100 to 120 compressions a minute, at least 2 inches deep and no more than 2.4, let the chest recoil fully, and keep the pauses short. When the AED arrives, power it on first, follow its prompts, clear everyone, and restart compressions straight after the shock.

  2. 02Airway management

    Expect to open the airway, size and place an adjunct and ventilate with a bag-mask device. The common miss is too much: breaths that are too big or too frequent. Give each breath over about a second, just enough to see the chest rise.

  3. 03The Megacode

    The instructor reads a case, you assign roles, and the rhythm on the monitor changes as you treat it. You pass by choosing the right branch each time and saying it as clear, closed-loop orders. Walk through five practice cases before the course day.

The written exam asks whether you know the algorithm. The Megacode asks whether you can say it out loud while the rhythm changes.

2025

What changed with the 2025 Guidelines

The current course follows the 2025 AHA Guidelines for CPR and Emergency Cardiovascular Care, released on October 22, 2025. Instructors had to switch to the new course materials by March 1, 2026, and the ACLS Provider Course was updated to the 2025 Guidelines when they were released. So the questions people ask about “new ACLS guidelines for 2026” are really about the 2025 set.

Most of the arrest algorithm stayed where it was. What catches people is study material from an earlier cycle that still ranks in search. If your notes say any of the left column, they are out of date:

Old study sheet versus the 2025 course
An older sheet saysThe 2025 course teaches
Atropine 0.5 mg for symptomatic bradycardiaAtropine 1 mg, repeated every 3 to 5 minutes, up to 3 mg in total; pacing or an infusion if it fails
Vasopressin as an alternative to epinephrineEpinephrine is the only vasopressor in the arrest algorithm: 1 mg every 3 to 5 minutes
IV or IO, whichever is quickerTry IV access first; IO when IV fails or would take too long
Cooling to 32 to 36 °C for 24 hours after ROSCDeliberate temperature control between 32 and 37.5 °C, for at least 36 hours if the patient stays unresponsive

Checked against the 2025 AHA Guidelines for CPR and Emergency Cardiovascular Care, October 2026. Exam preparation for trained providers, not treatment instructions.

Plan

How to pass the ACLS exam: a five-step plan

Most people start a week or two out, a little rusty on the drugs and unsure about the strips. That is enough time if each evening has one job.

  1. 01Clear the precourse line early

    Take the self-assessment as soon as your course gives you access. A first score under 70% is common and simply tells you which section to reread; practice the three sections here first if you want a dry run.

  2. 02Learn the arrest algorithm as one loop

    Two minutes of CPR, rhythm check, shock or no shock, drug, back to CPR. Say it out loud until the loop is automatic, then add where epinephrine and the antiarrhythmic fit in.

  3. 03Split the pulse algorithms by one question

    For bradycardia and tachycardia with a pulse, the first question is always “stable or unstable?”. Drill that decision on the algorithm flowcharts before memorizing any dose.

  4. 04Run a full practice deck, then fix one topic

    Take the 60-card practice test, read the score card, and reread only the lowest topic. The Study guide has a day-by-day version of this plan.

  5. 05Rehearse one Megacode out loud

    Pick a case from the Megacode practice page and talk through every order as team leader. Doing it once aloud beats reading it five times.

Hard?

Is the ACLS exam hard?

For most candidates it is moderately hard, and the difficulty sits in specific places. Concepts rarely trip people; recall under pressure does. The three usual weak spots are drug doses and their order, telling rhythms apart on a strip, and leading the Megacode without freezing.

Each one has a narrow fix. Doses stick when you meet them inside cases, a few each day. Strips settle by naming ten of them side by side on the precourse rhythm practice. The Megacode settles with one rehearsal out loud.

Renewal

ACLS certification and renewal

ACLS certification means an AHA ACLS Provider course completion card (eCard). It is a course completion card that employers and hospitals ask for, not a government license, and only an AHA Training Center or AHA instructor can issue the card. The card is valid for 2 years; cards are generally treated as valid through the end of the month printed on them. The AHA grants no grace period after that date, so book the renewal before it runs out.

ACLS renewal and recertification

Recertification is a shorter update course or HeartCode ACLS, with the exam and skills tests taken again. Nothing carries over from your last card, which is why the renewal course feels short but not easy. Start the plan above a week ahead and give the table of 2025 changes extra time: renewing providers are the ones most likely to carry an older dose in their head.

HeartCode ACLS and online courses

You can take the course as an instructor-led classroom course or HeartCode ACLS, a blended online-plus-skills path. HeartCode ACLS has an online part with simulated patient cases, then a hands-on skills session with an AHA instructor or a voice-assisted manikin. Either way, every AHA ACLS path ends in a hands-on skills test, so there is no fully online AHA ACLS card. A site that promises an AHA card with no hands-on part is describing something else.

Course formats and Training Centers are listed on the AHA ACLS course options page (opens the AHA site). For anything about your own card or eCard, your Training Center is the place to ask.

FAQ

Questions people ask

Is there a written test for ACLS?

Yes. Alongside the skills tests there is a written exam: usually about 50 multiple-choice questions (as AHA Training Centers report it; confirm the count with yours), with a pass mark of 84%, the figure Training Centers usually quote (your instructor confirms the exact rule).

How do I pass the ACLS written test?

Learn the arrest algorithm as one loop, split the pulse algorithms by “stable or unstable?”, then run a full practice deck and reread the lowest topic. The 60-card practice test shows which topic that is.

What are the actual answers for the ACLS written exam?

They are not published, and we do not reproduce them. Anything sold as the real answer key is either out of date or not the AHA exam. Our questions are original practice items, each with an explanation, so you learn why an answer is right rather than which letter to circle.

Can ACLS be taken online?

Partly: HeartCode ACLS has an online part with simulated patient cases, then a hands-on skills session with an AHA instructor or a voice-assisted manikin. In short, every AHA ACLS path ends in a hands-on skills test, so there is no fully online AHA ACLS card.

What are the new ACLS guidelines for 2026?

There is no separate 2026 set. Courses now teach the 2025 AHA Guidelines for CPR and Emergency Cardiovascular Care, released on October 22, 2025, with new materials required by March 1, 2026.

How long is ACLS certification valid, and how do I renew it?

The card is valid for 2 years. Renewal is a shorter update course or HeartCode ACLS, with the exam and skills tests taken again. There is no grace period, so plan it before the card runs out.
