Prepare for A+ with a blueprint-led plan

Certification overview

A+ is offered by CompTIA. Signals employable baseline competence for support roles and is frequently listed as a hard requirement for help desk and desktop support positions. This guide follows 220-1201 + 220-1202 (V15); always confirm provider changes before scheduling.

Who should pursue it

People entering IT support, desktop support, or help desk roles, and career changers who need a recognized first credential.

• You are entering IT without a formal technical background.
• You want a credential that maps directly to help desk and desktop support work.
• You prefer broad practical coverage over depth in one specialty.

Typical job roles

IT support, systems administration, networking, service operations, and infrastructure roles.

Skills measured

The current public standard organizes preparation into 9 domains. Each domain should be studied in the context of its linked objectives rather than as an isolated topic list.

• Core 1: Mobile Devices (13% of the published blueprint): Install, configure, and troubleshoot mobile-device hardware and connectivity.
• Core 1: Networking (23% of the published blueprint): Configure and troubleshoot common network technologies and services.
• Core 1: Hardware (25% of the published blueprint): Install, configure, and troubleshoot computer hardware and peripherals.
• Core 1: Virtualization and Cloud Computing (11% of the published blueprint): Apply foundational virtualization and cloud-computing concepts.
• Core 1: Hardware and Network Troubleshooting (28% of the published blueprint): Diagnose hardware and network faults using a structured process.
• Core 2: Operating Systems (31% of the published blueprint): Install, configure, and support desktop and mobile operating systems.
• Core 2: Security (25% of the published blueprint): Apply foundational endpoint, account, and physical security controls.
• Core 2: Software Troubleshooting (22% of the published blueprint): Diagnose operating-system, application, and security symptoms.
• Core 2: Operational Procedures (22% of the published blueprint): Apply safety, documentation, communication, and change procedures.

Official exam structure

The public profile lists Maximum 90 per core exam questions and 90 minutes. Supported preparation formats include Multiple Choice, Multiple Response, Scenario Decision, Drag and Drop Classification, Hotspot. The provider's delivery and scoring rules remain authoritative.

Recommended experience

No formal prerequisite. Around nine to twelve months of hands-on experience, including lab or home-lab work, is the usual recommendation.

Common candidate mistakes

The most avoidable errors are using an outdated objective list, over-studying familiar domains, memorizing practice wording, skipping practical work, and waiting until the final week to test timing.

Study strategy

Begin with a mixed diagnostic, map every miss to an objective, and rotate through focused study blocks. Combine source reading with labs, scenarios, or work artifacts where the blueprint expects applied judgment.

Time management

Practice within the 90-minute limit without forcing an identical pace on every item. Use a steady first pass, flag questions that warrant deeper analysis, and protect a final review window.

Practice exam strategy

Keep explanations on during targeted study and off during full simulation. Review incorrect answers, uncertain correct answers, domain balance, and pacing before deciding the next study action.

Exam-day strategy

Verify identification and delivery rules with the provider, arrive or check in early, read each prompt for the requested decision, and recover quickly after difficult items. Do not let one question consume the time needed for the rest of the exam.
