Start with the vendor’s exam objectives, plan your hours around the domain weightings, mix reading with hands-on practice, and use practice exams to find gaps rather than to collect scores. Most people need several weeks, and the right length depends on your experience. No trick replaces that, but a clear method makes the weeks count.
Step 1: Read the exam objectives first
Every vendor publishes a list of the skills an exam can test, usually grouped into domains with a percentage weighting. Download it before you buy anything else. It tells you what is in scope, how deep the vendor expects you to go, and which domains carry the most questions.
Then do a quick honest scan. Next to each objective, mark one of three labels: know it, partly know it, or never seen it. That sheet becomes your study plan. It also stops you from spending a week on a favorite topic that makes up five percent of the exam.
Check the exam code and version at the same time. Books, videos, and practice questions are written for a specific version, and a mismatch can send you down the wrong path.
Step 2: Decide how much time you need
Study time depends on your background, your pace, and the level of the exam. The ranges below are rough planning figures, not vendor numbers, and plenty of people fall outside them.
| Situation | Typical planning range |
|---|---|
| Fundamentals exam, new to the topic | 15 to 40 hours over 2 to 4 weeks |
| Associate-level exam, some hands-on experience | 40 to 80 hours over 4 to 8 weeks |
| Associate-level exam, new to the technology | 80 to 150 hours over 8 to 12 weeks |
| Expert or specialty exam | 100 to 200+ hours over 3 months or more |
Short, regular sessions beat rare marathons. Five sessions of an hour each week stay in memory better than one five-hour Sunday. If you can only study twice a week, extend the calendar rather than cram.
Step 3: Build a weekly schedule from the weightings
Split your total hours across domains in proportion to their weighting, then add extra time to the objectives you marked as unknown. A simple pattern for each week:
- Pick one or two domains.
- Learn the material from the vendor’s own learning content, a book, or a video course.
- Do hands-on work for the same topics.
- Write short notes in your own words.
- Finish with a small set of practice questions on just those topics.
Leave one buffer week at the end of the plan. Plans slip, and the buffer is where that gets absorbed.
Step 4: Learn actively
Reading and watching feel productive but fade quickly. These habits help the material stick:
- Explain it out loud. If you cannot explain a concept in two or three sentences, you do not know it yet.
- Write your own notes. Copying text word for word does not help. Rewrite it.
- Compare similar things. Exams love neighbors, such as two services that do almost the same job. Make a small table of how they differ.
- Ask why. For each answer, ask what would change if the requirement changed.
Step 5: Use spaced repetition
Memory fades unless you revisit what you learned. Spaced repetition means reviewing a topic at growing intervals: the next day, then after three days, then after a week, then after two or three weeks.
You do not need special software. Flashcards on paper or in an app work, as does a simple list of “things I keep forgetting” that you reread twice a week. Good candidates for cards are port numbers, limits, command names, definitions, and any rule that comes with an exception.
Keep each card small, with one fact per card. Remove cards you answer easily five times in a row.
Step 6: Get hands-on
IT exams ask what you would do, not only what a term means. Hands-on practice turns abstract facts into things you have seen.
- Use free tiers, trial accounts, or sandboxes that vendors provide.
- Build a small home lab, such as virtual machines on your own computer.
- Follow the vendor’s guided labs, then repeat the task without the instructions.
- Break things on purpose in a safe environment and fix them.
Do this even if your exam is mostly multiple choice. Some exams also include tasks where you work in a simulation or live environment, and hands-on time is the only real preparation for them. Always keep cost in mind: shut down paid resources when you finish a session.
Step 7: Use practice exams the right way
A practice exam is a measuring tool. It tells you what you know now, and it points to what to study next. It does not replace vendor learning material.
When to start. Take short quizzes on a domain right after you study it. Take your first full-length practice exam about halfway through your plan, when you have seen most of the material. Taking it too early is discouraging and not very informative; taking it too late leaves no time to fix the gaps it shows.
How to take one. Treat it like the real thing: a quiet space, the real time limit, no notes, no searching. Open-book attempts feel good and tell you little.
How to review mistakes. The review is where the learning happens. For every question you missed, and for every one you guessed right, write down:
- What the question was really asking.
- Why the right answer is right.
- Why your answer was wrong, and what led you there.
- The objective it belongs to.
Then sort the mistakes. Some are knowledge gaps (you did not know the fact), some are reading errors (you missed “least” or “first”), and some are judgment errors (you picked something valid but not the best). Each type needs a different fix: study, slow down, or compare trade-offs.
How to read the scores. Look at the result per domain, not only the total. One bad domain with two good ones needs targeted work. Aim to score comfortably above the passing mark several times in a row on different sets before you book. Practice results are an estimate, not a promise, because real exams differ in wording and difficulty.
Avoid memorizing practice questions. If you start recognizing answers by their wording, you are measuring memory of the test, not understanding of the topic. Our how we write our questions page explains how our practice sets are built.
Step 8: Plan the last week
The last week is for consolidation, not for new material.
- Seven to five days before. Take a final full-length practice exam under exam conditions. Review every miss.
- Four to three days before. Study only your weakest objectives. Reread your notes and run through flashcards.
- Two days before. Light review. Skim your “keep forgetting” list. Confirm your booking, time zone, and identification.
- The day before. Stop studying in the early evening. Prepare what you need, go to bed at a normal time.
If you test at home, run the system check from the testing provider well before exam day. Don’t wait for the final morning to find a problem with your camera.
Step 9: Be ready on exam day
- Eat something, drink water, and arrive or log in early.
- Bring accepted identification with a name that matches your registration.
- Read each question to the end. Notice words like “most cost-effective,” “first,” and “except.”
- Eliminate options you know are wrong, then choose among the rest.
- Manage time: check progress at the halfway point. If you are stuck, flag the question if the exam allows going back, and move on. Rules differ between vendors, so read them before you start.
- Answer every question. Some vendors state that unanswered questions score as wrong, so a guess can only help.
- If you fail, read the retake policy, review the score report by domain, and adjust your plan. A fail is information, not a verdict.
FAQ
How many practice exams should I take?
Enough to see steady results, usually three to five different sets, with careful review of each. The review matters more than the count.
Is it better to study every day?
Regular is better than long. Short daily sessions work well, but three or four steady sessions a week are fine if you keep them up.
Should I study with a group?
If you can, yes. Explaining topics to someone else shows what you really understand.
What if my practice scores stop improving?
Look at your error types. If the same domain keeps costing you points, go back to the learning material and do hands-on work for it, then retest on fresh questions.
