RAC Exam Preparation: Domains, Question Types, and Study Timing

The RAC exam is 120 multiple-choice questions in two and a half hours, built from a published content outline that weights each domain differently — and RAC-Drugs and RAC-Devices are not the same test. Both are administered by the Regulatory Affairs Professionals Society (RAPS), but they cover different domains at different weightings, because they’re built from a survey of two different job functions. Studying for one using the other’s outline wastes time on the wrong material.

This guide assumes you already know what RAC is, who administers it, and whether you’re eligible — see Regulatory Affairs Certification (RAC): What It Is and How to Get It for that. This page covers what the exam actually tests, how the two tracks’ content outlines differ, and how to build a study plan and timeline around them, using RAPS’s own 2026 candidate guides as the source.

What the RAC exam actually measures

Both RAC-Drugs and RAC-Devices share the same exam mechanics: 120 multiple-choice questions, a two-and-a-half-hour time limit, computer-based delivery at a Pearson VUE testing center or via online proctoring. RAPS builds each exam from three question formats, and knowing which one you’re facing changes how you should prepare for it:

• Recall questions ask for specific information directly — a regulation, a guidance document’s requirement, a definition tied to a stage of product development. These reward straightforward memorization of the primary sources.
• Application questions require relating that same knowledge to a situation a working regulatory professional would actually encounter — not “what does the rule say” but “what does the rule mean here.”
• Analysis questions present a short case or scenario and ask you to assemble information from it to identify and evaluate possible solutions — the format most resistant to rote memorization, since there’s no single fact to recall.

Because two of the three formats test judgment rather than recall, memorizing definitions is necessary but not sufficient — RAPS explicitly designs the exam around candidates who can reason through a regulatory scenario, not just cite the rule behind it.

RAC-Drugs domain weighting

RAC-Drugs content is reviewed annually and updated ahead of the Summer testing window, based on regulations and guidance in effect as of September 1 of the prior year. Per RAPS’s 2026 RAC-Drugs Candidate Guide, the exam content outline weights five domains (weightings are approximate, ±2%):

• Domain I — Regulatory Intelligence and Research (~27%): evaluating regulatory pathways and requirements, identifying health authority systems (CDER NextGen Portal, EU CTIS, FDA ESG, Drugs@FDA), interpreting regulatory decisions and their implications across the product lifecycle.
• Domain II — Submissions (~27%): analyzing submission requirements, preparing regulatory packages, managing the regulatory lifecycle, and reporting notifiable events to maintain compliance.
• Domain III — Collaboration (~13%): advising R&D and cross-functional teams, participating in risk management, understanding regulatory-authority inspection types, and coordinating with legal on regulatory implications.
• Domain IV — Strategy (~22%): risk/benefit and gap assessments, responding to regulatory-authority queries, managing post-marketing commitments, and preparing for health authority meetings.
• Domain V — Project Management (~11%): maintaining regulatory trackers, ensuring SOPs are in place, managing timelines, and managing vendors and external contracts.

Regulatory Intelligence and Submissions together account for roughly half the exam — the two domains most directly tied to reading and acting on primary regulatory text, which is consistent with the recall/application/analysis mix above.

RAC-Devices domain weighting

RAC-Devices runs on a separate cycle: content is updated ahead of the Spring testing window rather than Summer. Per RAPS’s 2026 RAC-Devices Candidate Guide, it weights four domains, not five, and they don’t map one-to-one onto the Drugs outline:

• Domain I — Strategic Planning (~27%): regulatory strategy from concept to obsolescence, researching predicate/equivalent devices, product-claim and testing-strategy review, and early engagement with regulatory agencies.
• Domain II — Design and Development (~27%): design verification/validation review, substantial-equivalence and state-of-the-art determinations, risk review participation, and evaluating the regulatory impact of design or manufacturing changes.
• Domain III — Process for Licensing, Registration, and Renewals (~23%): assembling and submitting filing data, responding to deficiency requests, updating registrations on critical changes, and customs/import-export documentation.
• Domain IV — Post-Market Activities (~23%): assessing product/QMS changes for regulatory impact, supporting reportability determinations, labeling-change assessment, and maintaining technical device files and dossiers.

The practical difference from Drugs: Devices splits its weight closer to evenly across four domains (27/27/23/23) rather than concentrating in two, and it has no separate “Collaboration” or “Project Management” domain — that work is folded into Strategic Planning and Post-Market Activities instead.

Where the exam content actually comes from

Both tracks draw on the same three-region split, with one difference in the “global” bucket. RAC-Drugs: roughly 30% US FDA requirements, 30% European regulations and guidance (European Commission, EMA, competent authorities), and 40% globally applicable practice — specifically ICH and WHO guidelines and standards. RAC-Devices uses the same 30/30/40 split, but its global bucket is IMDRF, WHO, and ISO standards instead of ICH — reflecting that device harmonization runs through IMDRF and ISO (see ISO 13485), not the ICH structure built for pharmaceuticals.

The practical implication either way: candidates who prepare only from FDA material are, by RAPS’s own design, leaving 70% of the exam uncovered. A GxP or quality-systems background helps with the globally-applicable domain, but doesn’t substitute for direct familiarity with the specific EU and international sources RAPS draws from.

Building a study plan

RAPS’s own preparation guidance, published alongside the content outline, comes down to three steps: review the content outline itself as a checklist, honestly assess your own strengths and gaps against each domain (a submissions-heavy role likely means a thinner Strategy or Project Management background, and vice versa), then build and implement a plan that allows enough time to close the gaps rather than just re-study what you already know. RAPS states plainly that there’s no single approach guaranteed to work, and that candidates who pass commonly report having spent several months preparing.

One way to apply that to the weightings above: allocate study time roughly in proportion to domain weight, not evenly across domains. For RAC-Drugs, that means Regulatory Intelligence and Submissions — the two ~27% domains — should get close to half your total study time between them, not a fifth each alongside the smaller Collaboration and Project Management domains. For RAC-Devices, Strategic Planning and Design and Development carry the same outsized share. RAPS also offers (but does not require) its own prep tools — practice exams, flashcards, courses, and books — built directly from the same content outline; using the outline itself as a diagnostic before reaching for any of them is what RAPS recommends candidates do first.

Timing: testing windows and when to start

RAC exams run in three annual testing windows — spring, summer, and autumn — scheduled through Pearson VUE, in person at a testing center or remotely via online proctoring. Results are typically released roughly 12 weeks after a testing window closes, reflecting the psychometric scoring RAPS performs across the full cohort rather than same-day automated results.

Two timing details matter for planning a study schedule specifically: content is revised annually and takes effect on different windows depending on track (Drugs before Summer, Devices before Spring), and because exam length, format, and content specifics are set by RAPS and can change between cycles, candidates should confirm current specifications against the current year’s official candidate guide (raps.org/rac-drugs-candidate-guide or raps.org/rac-devices-candidate-guide) before registering, rather than studying from a prior year’s version. Given the multi-month preparation window successful candidates typically report, working backward from your intended testing window — and checking which content vintage that window will test — is worth doing before you start studying, not after.

Frequently asked questions

How many questions are on the RAC exam, and how much time do I get?

120 multiple-choice questions in two and a half hours, for both RAC-Drugs and RAC-Devices. The exam expanded from 100 questions/2 hours starting with the Spring 2026 testing window.

What are the three RAC question types?

Recall (direct knowledge of a regulation or guidance), Application (applying that knowledge to a workplace scenario), and Analysis (assembling information from a short case to evaluate solutions). All three appear on both RAC-Drugs and RAC-Devices exams.

Do RAC-Drugs and RAC-Devices test the same domains?

No. Drugs has five domains (Regulatory Intelligence and Research, Submissions, Collaboration, Strategy, Project Management); Devices has four (Strategic Planning, Design and Development, Process for Licensing/Registration/Renewals, Post-Market Activities). The weightings and the underlying task statements are specific to each track — study from the candidate guide matching the exam you’re actually sitting.

How long should I study for the RAC exam?

RAPS doesn’t publish a fixed number, but states candidates who pass commonly report spending several months preparing, and recommends using the content outline as a self-assessment checklist before building a study plan rather than studying everything evenly.

When does new exam content take effect?

Annually. RAC-Drugs content updates ahead of the Summer testing window and is based on regulations and guidance in effect as of September 1 of the prior year. RAC-Devices content updates ahead of the Spring testing window. Always confirm against the current year’s candidate guide rather than a prior year’s.

Is RAC-specific prep material required?

No. RAPS offers optional practice exams, flashcards, courses, and books, but states its resources aren’t required — the content outline itself, published free in each candidate guide, is the authoritative basis for what’s tested.
