Why 30 questions and why 3 errors
In a 30-question test, a maximum of 3 mistakes means you need 27 correct answers: 90%. Use simulations to practise reading prompts and managing your time, then review the explanations when you finish.
Professional licences and their variants may require specific tests. Check your licence’s practice format and the official DGT requirements; the 30-question B simulation does not replace that preparation.
Our specific AM-licence simulation uses 20 questions, 20 minutes and a reference limit of 2 mistakes. Each licence has its own page with the corresponding practice information.
How to manage the 30 minutes during the exam
The most common trap isn't running out of time: it's the opposite. With time to spare, many candidates reread the prompts too often and induce their own doubts — they start switching correct answers to wrong ones. The practical rule: fast first pass (15–18 minutes), answer what you know for sure and flag the ones that block you. Second pass only on flagged questions, max 1 minute each. Third and final pass to double-check everything before submitting.
sacatelcarnet simulations show a visible timer — not as punishment, but to train your pace. After 5–10 timed simulations you should naturally finish in 18–22 minutes. If your simulation takes more than 28 minutes, you're still hesitating too much: you need more revision on the topics where you stop to think, not more tests.
How the 30 questions are spread across topics
We do not provide a guaranteed topic distribution for the official exam. Revise signs, priority, speed, alcohol and drugs, vehicle safety, traffic rules, manoeuvres and the other B-licence topics. Simulations combine questions from our practice bank.
Spend time on topics you find difficult while continuing to revise the whole syllabus. A simulation result can highlight questions to resolve, but it does not tell you what will appear in your exam.
Why people fail a 30-question test
The most common cause isn't lack of study: it's misreading the prompt. The DGT writes questions with decisive keywords — "always", "never", "except", "only", "at least" — and many candidates miss them. A prompt with "always" demands a categorical exception; one with "except in" admits the general rule minus one case. Switching answers because you doubt usually ruins a correct first instinct.
Second cause: studying only by topic and never doing full simulations. Knowing signage 100 % doesn't pass you if you've never trained the block-switching (sign → priority → mechanics → alcohol) under pressure. You need the random mix of a real simulation to get your head used to the topic-jumping.
Before deciding on a date, review your questions and outstanding topics. No sequence of practice scores guarantees a pass in the official exam. If you need help assessing your preparation, consult your instructor or driving school.

Frequently asked questions
- Why does the DGT exam have exactly 30 questions?
- This page explains 30-question practice for the common B-licence theory exam: 30 minutes and a maximum of 3 mistakes. Do not apply this format to every licence. For specific tests, consult your licence page and the DGT requirements.
- How many wrong answers are allowed on a 30-question test?
- A maximum of 3 wrong answers out of 30 to pass. At the fourth mistake the exam is failed, regardless of how many you got right. The real bar is 90 % accuracy: you need at least 27 correct answers.
- How long do I have to answer the 30 questions?
- 30 minutes in total — an average of 1 minute per question. In practice you don't need that much: most candidates finish in 15–20 minutes. The important thing is reserving the last 5 minutes for reviewing questions you flagged — order doesn't count and you can return to them before submitting.
- Is the 30-question test always for the same permit?
- The 30-question simulation on this page is for the B licence. When choosing another licence, check its page for the corresponding practice content and format. Specific tests do not necessarily use the same format as the common B theory exam.
- How many 30-question simulations should I do before the real exam?
- No number of practice tests guarantees a pass. Use your results to identify topics to revise, check that you understand the explanations, and alternate topic sessions with full simulations. A good practice score does not predict the result of the official exam.
- Are there picture questions on the 30-question test?
- Yes. The DGT exam includes image questions — sign photos, intersection diagrams, real traffic-situation photographs. Roughly half of the official bank carries visual support. The sacatelcarnet simulation replicates this format: picture questions appear with the photo or diagram, just like the real exam.
- Can I skip questions and come back to them?
- Yes. During the real exam you can answer in any order, skip questions and flag them for review. The screen shows a side panel with each question's status (answered, blank, flagged). Until you press "Submit" you can edit any answer. We recommend skipping the ones that block you, finishing the ones you know, and returning at the end with time and a cool head.
