CertDrill Getting Started: Choose an Exam, Unlock Practice, and Begin
A CertDrill getting-started guide: choose an exam by its full code, unlock access, then use domain practice and mistake review to plan study.
CertDrill organizes practice by full exam code, such as AIF-C01 or CLF-C02. The basic flow is: choose an exam → unlock access → practice → adjust review based on misses and domains.

1. Choose an exam
- Open CertDrill.
- Search by the full exam code, or browse by certification body and track.
- Open the exam page and confirm the summary, level, and domains match your goal.
Also read the official guide or a relevant study guide, such as the AIF-C01 study guide. Confirm the exam scope before unlocking a question bank.
2. Unlock access
The web app and the WeChat mini program IT知习 provide ways to unlock practice. Prices, duration, and entitlements follow the information shown at purchase time.
On the web
- Sign up or sign in to CertDrill.
- Open the practice page for your exam and go to its purchase entry.
- Follow the page instructions to purchase an activation code and unlock the exam.
- Check the status and expiration in your account history.
In the WeChat mini program
Search WeChat for IT知习, find the matching exam, and follow the instructions shown in the mini program. Payment options and entitlements depend on the current page.
Use access on both web and mini program
To see the same unlocked exams on both sides, sign in on the web and link the same account in the mini program. Access may not sync until the accounts are linked. If you need help, use the feedback entry on the website.
3. Start practicing
After unlocking, open the exam from Home or your library. Confirm the full exam code, then start with a short set to see which domains or scenarios need work.
4. Choose a practice mode
Available modes depend on the options shown on the exam page:
| Mode | Best for | How to use it |
|---|---|---|
| Sequential | First look at questions and explanations | Work through short sections to build familiarity |
| Random | Checking understanding beyond question order | Use during later review |
| By question type or domain | Targeting weak areas | Focus on recurring mistakes |
| Keyword search | Reviewing a scenario or term | Search with terms from missed questions |
| Mock exam | Checking timing and coverage before the exam | Complete a timed set, then review it |
| Wrong answers, favorites, and notes | Follow-up review | Return to material you have not mastered |
A practical sequence is to start with a few sequential or random questions, review weak domains, then use a mock exam to check readiness. Aim to understand the decision rule instead of memorizing item numbers or answer letters.
5. Review explanations
For each missed question, ask:
- Which domain does it test?
- Which condition in the question determines the answer?
- Why do the other choices fail to meet that condition?
If you repeat the same mistake, revisit the matching section of the official guide before trying similar scenarios. This helps separate a concept gap from poor scenario judgment or a missed constraint.
6. Example first-week plan
| When | Suggested activity |
|---|---|
| Day 1 | Read the official guide, confirm domains, and unlock the exam |
| Days 2–3 | Do a short sequential or random set each day and note why you missed items |
| Day 4 | Review misses and group them by concept, scenario judgment, or carelessness |
| Days 5–7 | Focus on the two weakest domains; add timed practice when ready |
At the end of the week, check whether you can explain the decision rules for your weakest domains and whether your misses matched your expectations. Use that to plan the next week.
