Failing the CompTIA A+ exam means a 14-day wait and $358 retake fee per exam part. CompTIA A+ is a two-part certification, which means you only need to retake the specific part you failed. This guide walks you through the complete retake process, explains what your score report tells you, and gives you a targeted study plan to pass on your next attempt.
A+ is the most popular entry-level IT certification in the world, but its broad coverage makes it deceptively challenging. The exam covers everything from hardware components and mobile devices to networking, security, cloud computing, and troubleshooting methodology. Many candidates underestimate the breadth of knowledge required, particularly for the performance-based questions that simulate real IT support scenarios.
CompTIA A+ is unique among IT certifications because it requires passing two separate exams. Core 1 focuses on mobile devices, networking, hardware, virtualization, cloud computing, and troubleshooting hardware and network issues. Core 2 covers operating systems, security, software troubleshooting, and operational procedures. Each exam contains up to 90 questions with a 90-minute time limit.
The passing scores differ between the two parts: Core 1 requires 675 out of 900, while Core 2 requires 700 out of 900. This means Core 2 has a slightly higher bar, which catches many candidates off guard. Both exams include a mix of multiple-choice questions and performance-based questions (PBQs) that simulate real-world IT scenarios like configuring a wireless router, setting up email on a mobile device, or troubleshooting a network connectivity issue.
If you fail one part, the good news is that your pass on the other part remains valid. You do not need to retake both exams. Simply focus your study efforts on the specific part you failed and schedule your retake after the mandatory 14-day waiting period. Both parts must be completed within the current exam version's availability window (typically 3+ years from release).
CompTIA enforces a standard retake policy across all their certifications, and A+ is no exception. After your first failed attempt, you must wait a minimum of 14 calendar days before scheduling your retake. This waiting period applies to every subsequent attempt as well. There is no limit on how many times you can retake the exam, but each attempt costs $358 USD.
The 14-day waiting period is actually beneficial. It gives you adequate time to analyze your score report, identify weak areas, adjust your study plan, and reinforce concepts before trying again. Candidates who rush to retake without proper preparation tend to fail again, wasting both time and money.
Consider purchasing a retake voucher bundle if available. CompTIA occasionally offers exam bundles that include a retake at a discounted price. These bundles can save you hundreds of dollars if you need a second attempt. Check the CompTIA store or authorized training providers for current bundle offers. Some bundles include both exam parts plus a retake for each at a package price.
Your score report is the most valuable tool for your retake preparation. After a failed attempt, CompTIA provides a detailed breakdown of your performance across each exam domain. The report uses a color-coded system or percentage bars showing how you performed relative to the passing threshold in each objective area.
For Core 1, the domains and weights are: Mobile Devices (15%), Networking (20%), Hardware (25%), Virtualization and Cloud Computing (11%), and Hardware and Network Troubleshooting (29%). For Core 2, the domains are: Operating Systems (22%), Security (24%), Software Troubleshooting (22%), and Operational Procedures (32%). Focus your retake preparation on domains where your score report shows the weakest performance.
Pay special attention to the troubleshooting domains, as they carry the highest weight in both exams. Core 1's Hardware and Network Troubleshooting is worth 29% — nearly a third of your score. Core 2's Operational Procedures domain is worth 32%. These domains require practical problem-solving skills rather than memorization, which is why they trip up candidates who study only from books.
Understanding what each Core 1 domain covers helps you focus your retake study:
Core 2 focuses on software, security, and operational skills:
Underestimating the exam breadth. CompTIA A+ covers an enormous range of topics across hardware, software, networking, security, cloud computing, and troubleshooting. Candidates who focus too narrowly on one area—like hardware—while neglecting networking, security, or operational procedures often fall short. The exam tests your ability across the entire IT support spectrum.
Skipping performance-based questions. PBQs appear at the beginning of the exam and can be intimidating. Some candidates skip them intending to return later but run out of time. PBQs are worth more points than standard multiple-choice questions. Practice PBQs extensively before your retake, and budget at least 20-25 minutes for them at the start of the exam.
Relying solely on memorization. While acronyms and port numbers require memorization, the exam emphasizes practical application. You need to understand why you would use a specific technology, not just what it is. Questions present scenarios and ask you to identify the best solution — this requires understanding, not just recall.
Poor time management. With up to 90 questions in 90 minutes, you have roughly one minute per question. Spending too long on difficult questions leaves insufficient time for easier ones. PBQs take longer than multiple-choice, so completing them first (or flagging them for later) is important for time management.
Not practicing with the command line. Both Core 1 and Core 2 test command-line proficiency. If you've never used ipconfig, ping, tracert, netstat, diskpart, sfc, or chkdsk from the command prompt, or ls, chmod, grep, and apt-get from a Linux terminal, you'll struggle with PBQs. Set up a virtual machine and practice these commands daily.
PBQs are simulation-style questions that test hands-on skills. On Core 1, you might need to configure a SOHO wireless router (setting SSID, security protocol, channel, DHCP range), set up a network with proper IP addressing, or troubleshoot hardware issues by dragging components to the correct locations. On Core 2, expect scenarios involving operating system installation, command-line operations, security configuration, or malware removal procedures.
The best way to prepare for PBQs is to build a home lab. Install Windows 10/11 and a Linux distribution (Ubuntu is recommended) in virtual machines using VirtualBox or VMware Workstation Player (both free). Practice using the command line for both operating systems. Configure network settings, manage user accounts, set up shared folders, configure Windows Firewall rules, and troubleshoot common issues. This hands-on experience translates directly to exam performance.
During the exam, consider flagging PBQs and returning to them after completing the multiple-choice questions. This ensures you collect easier points first and can dedicate remaining time to the more complex simulation scenarios without the pressure of unanswered questions behind you. However, don't leave PBQs for the last 5 minutes — allocate at least 20-25 minutes for them.
At $358 per exam part, retakes add up quickly. Here are several strategies to reduce your costs:
You must wait 14 calendar days after each failed attempt before scheduling your retake. This applies to every subsequent attempt with no escalation.
$358 USD per exam part. Since A+ has two parts (Core 1 and Core 2), you only pay for the specific part you need to retake.
Core 1 requires 675 out of 900, and Core 2 requires 700 out of 900. Both exams are scored on a scale of 100-900.
There is no limit on retake attempts. You can retake the exam as many times as needed, with a 14-day waiting period between each attempt.
No. Each part is scored independently. Passing Core 1 remains valid while you prepare for and retake Core 2, as long as you complete both within the exam version's availability window (typically 3+ years).
Standard vouchers can be used for retakes. However, discounted academic or promotional vouchers may have restrictions. Always check your voucher terms before scheduling a retake.
Many candidates underestimate A+ because it is entry-level. It covers an extremely broad range of topics including hardware, networking, security, operating systems, cloud computing, and troubleshooting, making thorough preparation across all domains essential.
