Lesson 1: How the 220-1202 Exam Works and How This Course Maps to It

Why start here

Before you study any technology, you need to know what you are preparing for. This level sets out the facts of the CompTIA A+ Core 2 (220-1202) exam, how its content is weighted, and what this course does and does not do.

Do this now: open a notes file called "220-1202 exam facts". You will fill it in as you read.

Task 1: Record the exam facts

CompTIA publishes these test details for A+ Core 2 (220-1202):

Read three of these carefully:

1. "Maximum of 90" is a ceiling. Your exam may have fewer questions. It will not have more.
2. 700 is a scaled score, not a percentage. The scale starts at 100, not 0, so 700 does not mean "70% correct". Do not try to convert it into a number of questions.
3. Recommended experience is a recommendation. It is not an entry requirement. This course assumes no prior knowledge.

A simple time check: 90 minutes for up to 90 questions averages about one minute each. Some questions take longer, so pace matters.

Task 2: Understand the two question types

• Multiple-choice. You read a question and select from listed options. Some have one correct answer (single response). Others ask you to select more than one (multiple response).
• Performance-based. CompTIA defines performance-based questions (PBQs) as exam items designed to test a candidate's ability to solve problems in real-world settings. You perform a task instead of only picking an answer.

Think of a driving test: the written part checks what you know, and the practical part checks what you can do. A PBQ is the practical part.

Do this: in every later level, do not stop at memorising a term. Ask, "What would a technician see on screen, and what would they do next?" That is the reasoning PBQs reward.

Task 3: Know what earns the certification

A+ is one certification earned through two exams:

1. Core 1 (220-1201)
2. Core 2 (220-1202)

You must pass both. Passing Core 2 alone does not make you A+ certified. CompTIA also states that the two exams must come from the same version, so pair 220-1202 with 220-1201 and not with an older Core 1 exam.

This course covers Core 2 only.

Task 4: Learn the four domains and their weights

The exam content is split into four domains (major subject areas). Each has a published percentage of the examination.

What each domain covers, in plain terms:

• 1.0 Operating Systems: installing, configuring and using Windows, macOS, Linux and mobile operating systems.
• 2.0 Security: protecting devices, accounts, networks and data.
• 3.0 Software Troubleshooting: diagnosing and fixing software and security problems on PCs and mobile devices.
• 4.0 Operational Procedures: documentation, safety, backups, professionalism and similar working practices.

Do this: budget study time by weight. The first two domains together make up 56% of the exam. Operational Procedures is the smallest, but at 21% it is still roughly one fifth. Do not skip it.

Task 5: Know what "Windows" means

The objectives include a note on Windows versions. Where an objective does not name a specific version, it can include content related to Windows 10 and Windows 11.

Do this: whenever this course says "Windows", expect to know how the task looks in both versions.

Task 6: Read the objective lists correctly

CompTIA's objectives list examples under each topic as bullet points. CompTIA states these lists are not exhaustive. Other examples of technologies, processes or tasks pertaining to each objective may appear on the exam even if they are not listed.

Do this: learn the concept behind each bullet, not only the bullet's wording.

Task 7: Know what this course is, and is not

• Independent. This course is not affiliated with, authorized by, or endorsed by CompTIA.
• Original questions only. Every practice question here is written for this course. None is a real exam question, and none will ever be presented as one.
• No guarantee. No course can promise a pass. Your result depends on your preparation and your performance on the day.

Task 8: Stay away from "brain dumps"

A brain dump is unauthorized material that reproduces actual exam content. CompTIA's objectives describe these as content from "unauthorized third-party training sites".

The objectives document states that individuals who use such materials will have their certifications revoked and be suspended from future testing, in accordance with the CompTIA Candidate Agreement. Every candidate is required to abide by that agreement.

Why CompTIA prohibits them:

• The certification is meant to verify knowledge and skills. Memorised answers verify neither.
• CompTIA protects the security of its questions so results stay meaningful to employers.

Do this, in order, when you find new study material:

1. Check whether it claims to contain "real" or "actual" exam questions.
2. If it does, stop using it.
3. If you are unsure, contact CompTIA at examsecurity@comptia.org to confirm.
4. Review CompTIA's Certification Exam Policies before you continue studying.

What the exam asks about this

The exam does not test its own format. These facts serve your preparation:

• Plan your pace for up to 90 questions in 90 minutes.
• Expect scenario questions that begin "Given a scenario…" and ask for the best next action.
• Expect to apply knowledge in performance-based questions, not only recall it.
• Expect Windows content from both Windows 10 and Windows 11.

Key takeaways

• Maximum of 90 questions, 90 minutes, multiple-choice and performance-based.
• Passing score: 700 on a scale of 100–900. It is not a percentage.
• A+ requires both Core 1 (220-1201) and Core 2 (220-1202).
• Domains: 1.0 Operating Systems 28%, 2.0 Security 28%, 3.0 Software Troubleshooting 23%, 4.0 Operational Procedures 21%.
• "Windows" means Windows 10 and Windows 11.
• Bulleted examples in the objectives are not exhaustive.
• This course is independent of CompTIA, uses original practice questions only, and promises no pass.
• Brain dumps risk certification revocation and suspension from future testing.
