How Hard Is A+ Core 1? What the 220-1201 Really Tests

How hard is A+ Core 1? For an entry-level exam, harder than people expect, and almost entirely because of width. The 220-1201 has no single brutal topic. Instead it asks about laptop batteries, Wi-Fi bands, DDR generations, fiber connectors, RAID levels, printer maintenance kits and cloud service models, then gives you a broken machine and asks what to check first. You get a maximum of 90 questions in 90 minutes, and you pass at 675 on a scale of 100 to 900.

If you have spent a year or so fixing hardware, most of it will look familiar and the challenge is filling gaps. If you are new to IT, the volume of small facts is the wall, and the troubleshooting scenarios are where that wall shows. For the exam itself, format, domains and what A+ gets you, start with what CompTIA A+ Core 1 is. This post is only about difficulty.

Why does Core 1 feel so wide?

Core 1 has 27 objectives across five domains, and most of them are lists of things to recognize. A few examples of what one exam can ask you to tell apart:

• Hardware specs. DIMM versus SODIMM, which DDR generation fits which slot, ECC versus non-ECC, and why two RAM sticks in the wrong slots do not give you dual-channel.
• Connectors and cables. SC, LC and ST fiber connectors, T568A versus T568B, plenum versus non-plenum, which video and peripheral cables carry what.
• Storage and RAID. SATA versus NVMe, the minimum disk count for RAID 5, 6 and 10, and how many failures each level survives.
• Printers. Laser, inkjet, thermal and impact each have their own maintenance steps, and the exam will mix them in one question.
• Mobile. Field-replaceable laptop parts, docking stations versus port replicators, Bluetooth pairing, MDM.
• Networking. The TCP and UDP port set, DNS record types, DHCP reservations versus exclusions, cable modem versus DSL modem versus ONT.

None of these is conceptually difficult. The difficulty is that there are hundreds of them, they are similar enough to blur, and the exam writes its wrong answers from the neighbors. Hardware (25%) and Networking (23%) together are nearly half the exam, and both are dense with this kind of recall. The Core 1 domains explained post walks through all five if you want the full map.

Can you work out how many questions you can miss?

CompTIA sets the Core 1 passing score at 675 on a scale of 100 to 900. It is a scaled score, and CompTIA does not publish how raw answers are converted into it. That means 675 is not a percentage of questions you need right, and you cannot reliably work out a "number to get correct" from it. Anyone who gives you one is guessing.

A useful contrast: Core 2 (220-1202), the other half of A+, has its own passing score of 700 on the same 100 to 900 scale. The two exams are scored separately. Passing one does not carry points into the other, and you need both for the credential. If you are weighing which to sit first, A+ Core 1 vs Core 2 covers the sequencing question.

CompTIA also publishes no pass rate for 220-1201, so any figure quoted online is not CompTIA's. Aim to be solid in every domain, and judge readiness by your score on practice questions you have not seen before, broken down by domain.

Why does the troubleshooting domain decide so many results?

Domain 5, Hardware and Network Troubleshooting, is the largest at 28%. All six of its objectives are written as "given a scenario": troubleshoot motherboards, RAM, CPUs and power; drives and RAID; video and displays; mobile devices; networks; printers. You are not asked to define anything. You are given symptoms and asked for the cause or the next action.

This is where breadth turns into a real problem. To diagnose a printer that produces ghost images, you need to know what a drum and a fuser do. To handle a failed disk in a RAID 5 array, you need to know what parity protects. In effect, Domain 5 is a second test of the other four domains, written as symptoms.

Here is the kind of item Domain 5 produces, from the practice bank in our book:

A user reports that a desktop PC randomly shuts down without warning (no BSOD, no OS shutdown sequence) but only when running demanding games or video encoding tasks. The machine runs fine during light tasks. What should the technician check first?

A. Run an extended memory diagnostic overnight

B. Check CPU temperature and substitute the power supply

C. Roll back the GPU driver to the previous version

D. Replace the motherboard's CMOS battery

The answer is B. A hard power-off that only happens under load, with no crash screen, points to thermal shutdown or a power supply that sags when current draw rises. Memory faults and driver faults tend to produce crash screens, and the CMOS battery affects the clock and firmware settings. The trap is answer A: blaming RAM is a common reflex, but the book's explanation points out that memory faults tend to show up as crash screens or crashes across workloads, not as a silent power-off that tracks load.

What do performance-based and drag-and-drop questions involve?

CompTIA lists the Core 1 question types as multiple-choice (single and multiple response), drag-and-drop, and performance-based. It does not say how many of each you will get, so do not plan around a number you read somewhere.

What matters is what these items test. A multiple-choice question lets you recognize the right answer. A drag-and-drop or performance-based item makes you produce it: put steps in order, match a cable to a connector, choose settings for a small office router, pick parts for a workstation build. Recognition is not enough when there are no options to recognize.

Ordered steps are a favorite, and the distractors are built by swapping two of them. Mobile pairing, printer maintenance and SOHO router setup all lend themselves to this, because each has a sequence where one step depends on the one before.

The fix is practice in the same shape. Write out sequences from memory. Build a mock SOHO configuration on paper. Our Core 1 practice questions walkthrough works through several scenario items in detail.

Will you run out of time on Core 1?

Usually, if you do not get stuck. A maximum of 90 questions in 90 minutes works out to roughly a minute an item. Most recall questions take far less than that: you either know the RAID 6 minimum disk count or you do not. Scenario and performance-based items take longer, and they are where the clock disappears.

The pacing risk on Core 1 is a performance-based item you only half understand. It is easy to spend ten minutes on one, and that time comes out of thirty questions you could have answered quickly. Decide before exam day how long you will give any single item before making your best choice and moving on.

Which look-alike answers catch people?

Our study guide flags a common pitfall for every objective. These come up again and again, because each pairs two things that look alike:

In every row, the tempting answer would be right if one detail in the stem were different. Spotting that detail (after a screen repair, only under load, every 20 minutes) is most of the skill.

How hard is A+ Core 1 for newcomers, technicians and hobbyists?

Harder for people starting from zero. Career changers meet ports, connectors, RAM standards and printer types all at once, and the recall load is heavy before the scenarios even begin. It is also harder for people who studied from short videos alone. Those are fine for orientation, but they rarely drill the fine distinctions the wrong answers are built from.

Easier for desktop support and repair technicians who have opened cases, swapped drives and cleared print queues. CompTIA recommends 12 months of hands-on experience in an IT support specialist role, and that recommendation exists for a reason: the symptoms will look familiar. Their risk is a different one. Experienced techs answer the way their own shop does it, skip the data backup before replacing a failing drive, or never touched the technologies their workplace does not use, such as impact printers or satellite links.

Somewhere in between are people strong on one side. A networking hobbyist may fly through Domain 2 and stumble on laptop internals and printer maintenance. A hardware builder may know every RAM spec and lose points on DNS records and DHCP.

How do you make Core 1 easier?

Treat it as two jobs. First, build the recall base across all five domains, weighted toward Hardware, Networking and Troubleshooting. Second, practice applying it to symptoms, because Domain 5 is the largest domain and it rewards diagnosis, not definitions.

Track your practice results by domain, not as one overall score. A 70% average can hide a weak Troubleshooting result, and on a 28% domain that is the gap that matters. The A+ Core 1 study plan lays out how to split the weeks.

If you want the recall and the scenario practice in one place, the CompTIA A+ Core 1 220-1201 Study Guide gives each objective its own section with an Exam Tip and a Common Pitfall callout, which is where the traps above come from.

FAQ

Which Core 1 domain should I worry about most?

Hardware and Network Troubleshooting, at 28%. Every one of its objectives is a scenario, and each assumes you already know the hardware, networking or mobile topic behind it. If you are new to IT, the printer and networking recall that feeds those scenarios is usually where the gaps show.

What percentage do I need to pass A+ Core 1?

CompTIA does not express the pass mark as a percentage. The passing score is 675 on a scaled range of 100 to 900, and CompTIA does not publish the conversion from raw answers to that scale. Prepare to be competent across every domain rather than aiming at a number of correct answers.

Can I pass A+ Core 1 with no IT experience?

Yes, there is no experience requirement, so anyone can book it. CompTIA recommends 12 months of hands-on IT support work, but nobody checks it. Without that background, plan extra time for the recall material and for scenario practice, because the troubleshooting domain assumes you can picture the hardware.
