5. Written Test Study Guide: 7-day Pass Plan

With this 7-day study plan and free app practice, most learners can comfortably pass the Part A written test first time:

Day Study content Suggested time App features to use
Day 1–2 Read the Road Users' Code + sequential app practice (traffic signs) 1.5 hours daily Sequential practice mode
Day 3–4 Sequential app practice (road markings and driving rules) + flag incorrect answers 1.5 hours daily Sequential practice + bookmarks
Day 5 Focus on flagged incorrect answers + take 2 mock tests 1 hour Bookmark review + mock tests
Day 6 100 random practice questions + take 3 mock tests 1.5 hours Random practice + mock tests
Day 7 Final preparation before the test: take 3 mock tests, aiming for at least 18/20 each time 1 hour Mock tests

✅ Secret to passing: Once you score at least 18 correct answers in 3 consecutive mock tests, you are ready for the real written test! The key is repeatedly reviewing incorrect answers, rather than doing new questions.

6. Commonly Missed Written Test Questions

Based on years of learning with a private instructor teaching experience, these are the question categories learners most often get wrong:

❌ 5 Most Commonly Missed Question Types

  1. Confusing speed limit signs: For example, is the limit near a school 50km/h or 30km/h? Answer: the general speed limit is 50km/h unless otherwise signed
  2. Giving way at roundabouts: Give way to vehicles already in the roundabout; many people confuse left and right
  3. Double white line rules: With double white lines, you cannot cross if the line nearest you is solid; if the nearest line is broken, you may cross to overtake
  4. Calculating safe distances: The following distance uses the “2-second rule”; many people answer “2 metres” or “2 car lengths”
  5. Drink-driving legislation: The blood alcohol limit is 50mg/100ml; do not confuse it with breath test figures

7. Failed the Written Test? Guide to Early Retest Slots

There is no need to worry too much if you fail the written test — retest procedures are simple and waiting times are much shorter than for road tests:

  • Retest fee: $510 (reapply for the entire test)
  • Waiting times vary by test category and region. Please refer to the latest shared test waiting-time information
  • Early slot tip: Check the Transport Department website daily for cancellations; the most early slots appear from Sunday evening to Monday morning
  • Waiting period: There is no mandatory waiting period for the written test; you can book again immediately after failing

For more details on driving test waiting times and early retest slots, see our dedicated article.

⚠️ Money-saving tip: Failing the written test costs another $510 test fee and time waiting for a new appointment. Use an app until you consistently score 18/20 before taking the test. Driving lessons are already expensive, so avoid spending more on retests! For a full driving lesson costs breakdown, see our cost guide.

8. Frequently Asked Questions

Most written test apps base their questions on the Transport Department's Road Users' Code, closely matching the real test's scope and format. However, the Transport Department does not publish its full question bank, so app questions are mock questions and may differ slightly from actual test questions. If you consistently score above 18/20 in the app, the real test should be no problem.
We recommend using both. Apps provide question practice, while the Road Users' Code is the official test material and explains concepts in greater detail. Spend at least 1–2 hours reading through it once; app questions will then be easier to understand.
Most learners can pass first time after studying with an app for 3–7 days (1–1.5 hours daily). The key is consistently passing mock tests. If you have driving experience or basic knowledge of traffic rules, even 2–3 days may be enough.
In the driving licence application process, you can choose to pass the written test before booking the road test, or apply for a combined test (written and road tests on the same day). We recommend passing the written test first: if you fail the written part of a combined test, you cannot take the road test, wasting your waiting time.
The written test generally does not require a private instructor to teach you specifically; self-study with an app is enough. However, if you enrol on a driving school course, some schools include written test tuition. For learners using CEF Driving Courses, school courses usually also include written test preparation.
A written test pass is valid for 2 years. You must pass the road test within 2 years of passing the written test, or the result expires and you need to retake it. Start lessons and book your road test promptly after passing. You can immediately WhatsApp APASS for instructor matching!
