The CompTIA A+ certification requires passing two separate exams — Core 1 and Core 2 — each containing up to 90 questions with a 90-minute time limit. This means you face a total of up to 180 questions across both exams, making A+ one of the most comprehensive entry-level IT certifications available. Understanding the format, question types, and domain weightings for each exam is essential for efficient preparation and first-attempt success.
As the industry's most widely recognized entry-level IT certification, CompTIA A+ validates foundational technology skills across hardware, software, networking, and security. According to PrepForCerts analysis, over 1.3 million professionals hold the A+ certification, and it consistently appears in the top 3 most-requested certifications for IT help desk and desktop support positions.
Unlike most IT certifications that require a single exam, A+ requires passing both Core 1 and Core 2. Each exam is independent — you can take them in any order, on different days, and even use different testing centers. However, both must be passed within a reasonable timeframe (CompTIA does not enforce a strict window between exams, but recommends completing both within 6 months).
Core 1 focuses on the physical and networking aspects of IT support. The passing score is 675 out of 900 (approximately 75%). This exam is considered slightly easier by most candidates because the content is more concrete and visual — you either know what a RAM slot looks like or you do not.
| Domain | % of Exam | ~Questions | Key Topics |
|---|---|---|---|
| Mobile Devices | 15% | ~14 | Laptop hardware, mobile device configuration, connectivity |
| Networking | 20% | ~18 | TCP/IP, ports, protocols, Wi-Fi, network troubleshooting |
| Hardware | 25% | ~23 | Motherboards, CPUs, RAM, storage, peripherals, power supplies |
| Virtualization & Cloud | 11% | ~10 | Cloud models, virtualization concepts, cloud storage |
| Hardware & Network Troubleshooting | 29% | ~26 | Troubleshooting methodology, hardware/network issues |
Core 2 covers operating systems, security, software troubleshooting, and operational procedures. The passing score is 700 out of 900 (approximately 78%) — higher than Core 1, reflecting the slightly more complex nature of software and security concepts.
| Domain | % of Exam | ~Questions | Key Topics |
|---|---|---|---|
| Operating Systems | 22% | ~20 | Windows, macOS, Linux, Chrome OS installation and features |
| Security | 24% | ~22 | Malware, social engineering, encryption, authentication, physical security |
| Software Troubleshooting | 22% | ~20 | OS issues, application problems, browser troubleshooting |
| Operational Procedures | 32% | ~29 | Documentation, change management, disaster recovery, professionalism |
Both Core 1 and Core 2 use the same question format mix:
Single-answer questions present four options with one correct answer. These are straightforward knowledge tests. Multiple-answer questions explicitly state how many options to select (e.g., "Choose TWO") — you must select exactly the right number for full credit. No partial credit is awarded.
PBQs are simulated environments where you must complete tasks hands-on. Typically 3-5 PBQs per exam, appearing at the beginning. Common PBQ scenarios include:
PBQs typically take 5-10 minutes each. The recommended strategy is to flag them and return later after completing the multiple-choice questions. This ensures you answer the maximum number of questions even if you run short on time for PBQs.
These require matching items or placing them in the correct order. Examples include matching port numbers to protocols, ordering troubleshooting steps, or classifying hardware components by category. They test organizational knowledge and systematic thinking.
With approximately 1 minute per question, time management is critical on A+ exams. Here is a proven approach:
| Certification | Questions | Time | Passing Score | Cost | Focus |
|---|---|---|---|---|---|
| CompTIA A+ (2 exams) | Up to 90 each | 90 min each | 675-700/900 | $716 total | Hardware, OS, networking, security |
| CompTIA ITF+ | Up to 75 | 60 min | 650/900 | $139 | IT fundamentals (pre-A+) |
| Google IT Support | Coursework | Self-paced | 80% per course | $49/month | IT support foundations |
| Microsoft MD-102 | 40-60 | 120 min | 700/1000 | $165 | Windows endpoint management |
| Cisco CCT | 60-70 | 90 min | Variable | $165 | Cisco hardware support |
A+ offers the broadest coverage of any entry-level IT certification. While the $716 total cost is higher than alternatives, its universal recognition by employers and the breadth of topics covered make it the strongest foundation for an IT career. According to PrepForCerts analysis, A+ certified professionals earn $5,000-$10,000 more annually than non-certified peers in help desk and desktop support roles.
| Experience Level | Core 1 Prep | Core 2 Prep | Total Time |
|---|---|---|---|
| Complete beginner | 6-8 weeks | 6-8 weeks | 12-16 weeks |
| Some IT exposure | 4-5 weeks | 4-5 weeks | 8-10 weeks |
| Help desk experience | 3-4 weeks | 3-4 weeks | 6-8 weeks |
Most candidates take Core 1 first because hardware and networking concepts provide the foundation for Core 2's software and security topics. However, if you have strong software skills but limited hardware experience, you could start with Core 2 to build confidence with a first-attempt pass.
Focus your study time on the highest-weighted domains:
| Aspect | Core 1 | Core 2 |
|---|---|---|
| Focus | Hardware, networking, mobile | Software, security, operations |
| Passing Score | 675/900 (75%) | 700/900 (78%) |
| Difficulty Perception | Easier (more concrete topics) | Harder (more abstract concepts) |
| PBQ Types | Network config, hardware ID | OS config, security setup |
| Study Approach | Visual + hands-on labs | Scenario practice + memorization |
The CompTIA A+ Core 1 exam contains up to 90 questions to be completed in 90 minutes. Questions include multiple-choice, multiple-select, drag-and-drop, and performance-based questions (PBQs).
You have 90 minutes per exam for both Core 1 and Core 2. This gives you approximately 1 minute per question, making time management critical — especially with PBQs that can take 5-10 minutes each.
Core 1 requires 675 out of 900 (approximately 75%), and Core 2 requires 700 out of 900 (approximately 78%). Both exams must be passed to earn the A+ certification.
PBQs are generally more challenging because they require hands-on problem-solving in simulated environments rather than simple recall. They test real-world skills like configuring networks and troubleshooting hardware.
Yes, CompTIA allows you to take the exams in any order. Most candidates start with Core 1 since hardware topics provide foundational context for Core 2's software and security content.
Each exam costs $358, so the total for both Core 1 and Core 2 is $716. CompTIA offers bundles and retake vouchers that can reduce the effective per-attempt cost.
Typically 3-5 PBQs appear per exam, usually at the beginning. They cover hands-on scenarios like configuring wireless networks, setting up email clients, partitioning drives, and troubleshooting connectivity.
Most candidates need 8-12 weeks total (4-6 weeks per core exam) studying 1-2 hours daily. Those with help desk experience may prepare faster, while complete beginners should allow 12-16 weeks.
