Which CompTIA A+ domains need the most study hours?
An objective domain is a named topic area on an exam. Each domain carries a fixed percentage of the test. Multiply that percentage by your hours for one exam. The figures below use 70 hours per exam, the midpoint of the 60 to 80 hour beginner estimate. That is an estimate, not a CompTIA figure.
| Exam | Objective domain | Weight on exam | Hours at 70 h per exam |
|---|
| Core 1 | Hardware and network troubleshooting | 28% | 19.6 h |
| Core 1 | Hardware | 25% | 17.5 h |
| Core 1 | Networking | 23% | 16.1 h |
| Core 1 | Mobile devices | 13% | 9.1 h |
| Core 1 | Virtualization and cloud computing | 11% | 7.7 h |
| Core 2 | Operating systems | 28% | 19.6 h |
| Core 2 | Security | 28% | 19.6 h |
| Core 2 | Software troubleshooting | 23% | 16.1 h |
| Core 2 | Operational procedures | 21% | 14.7 h |
Hardware and network troubleshooting is the biggest Core 1 domain at 28 percent. At 70 hours per exam, that is 19.6 hours. Operating systems and security tie for the biggest Core 2 domains at 28 percent each, or 19.6 hours each. Virtualization and cloud computing is the smallest area, at 11 percent, or 7.7 hours.
- Hardware and network troubleshooting - finding a fault in a laptop, printer, or network.
- Hardware - the physical parts of a computer and how to install and maintain them.
- Networking - connecting devices so they can share data.
- Mobile devices - phones and tablets, their settings and support tools.
- Virtualization and cloud computing - running extra computers inside one machine.
Give the largest domains your longest sessions. Give the smallest ones a shorter block near the end.
How do Core 1 and Core 2 differ?
The official CompTIA V15 exam spec lists the details below. Each exam allows up to 90 questions in 90 minutes. The mix includes multiple choice questions, drag-and-drop questions, and performance-based questions that use a live system.
| Attribute | A+ Core 1 (220-1201) | A+ Core 2 (220-1202) |
|---|
| Launch date | March 25, 2025 | March 25, 2025 |
| Maximum questions | 90 | 90 |
| Time limit | 90 minutes | 90 minutes |
| Passing score | 675 / 900 | 700 / 900 |
| Recommended experience | 12 months hands-on in an IT support role | 12 months hands-on in an IT support role |
| CertMaster study hours | Learn 25-40 h, Practice 10-20 h, Labs 15-25 h | Learn 25-40 h, Practice 10-20 h, Labs 15-25 h, Perform 30-60 h |
Is the CompTIA A+ worth the months it takes, and where does it lead?
Questions about comptia a+ how long does it take usually ignore what follows the certificate. The Bureau of Labor Statistics Occupational Outlook Handbook tracks this occupation. It reports a median annual wage of $61,860 for computer user support specialists as of May 2025. It reports $109,470 for all computer occupations. The source lists 903,100 support specialist jobs in 2025 and projects a 3 percent decline through 2035. That is 24,300 fewer jobs. About 48,700 openings arrive each year, and most replace someone who left.
The same page notes that a high school diploma plus IT certifications can qualify you for support roles. That includes user support and network support specialist roles.
CompTIA's IT Career Insights 2026 report was fielded in July and August 2026. It found that 81 percent of IT professionals view its certifications as relevant. Eighty-four percent report at least one realized benefit. A stronger resume is the most common benefit at 50 percent, and greater confidence follows at 49 percent. Sixty-eight percent say certification helped their career. Twenty-nine percent of those employed when certified received a pay increase or bonus.
The A+ is a starting point, not a finish line. To see what the voucher and retake fees add up to, read the CompTIA A+ certification cost breakdown. Compare the CompTIA Security+ exam cost and the best cyber security certifications in 2026. A degree is not always part of the plan. See the best IT certifications without a degree.
What are your next steps?
Pick your weekly budget first. It decides every other date. Then find your row in the grid and write the end week on a calendar. Buy each voucher when you are close to the sitting date.
- Choose a budget you can hold for 8 to 16 weeks, not one you can hold for a weekend.
- Book Core 1 first if your hands-on work is on hardware and troubleshooting.
- Book the second exam once your practice scores sit above 85 percent.
- Add a re-study block for a second attempt, and a two week wait in case of a third.
Read the official objective lists for both exams before your first session. They show you where every hour goes.
