Common TLC Exam Mistakes and How to Avoid Them

Mistake one: reading instead of testing

Reading material feels like studying and produces almost no retrieval practice. You finish a page with a comfortable sense of familiarity and no evidence that you could produce the fact under pressure.

The fix is to lead with questions. Take a full practice test before you study anything, use question practice as your main method rather than your final check, and treat reading as the thing you do after a question exposes a gap.

Mistake two: reviewing only the wrong answers

Reviewing only what you got wrong is efficient and misleading, because it hides every question you guessed correctly. A lucky guess and real knowledge look identical on a score report and behave very differently on exam day.

The fix takes two seconds a question: before answering, note whether you are certain or guessing. Review every guess regardless of outcome. Your review list gets shorter and far more honest.

Mistake three: studying only the sections you enjoy

People drift toward the categories they score well in, because it feels good. With a 70% pass mark, that is exactly backwards — marks are cheapest where you are weakest.

The fix is arithmetic. After each mixed test, write the score for each category. Spend the next block of time on the lowest two, and do not return to your strongest category until the weak ones clear the pass mark on their own.

Mistake four: never practising against the clock

Untimed practice measures knowledge. The exam measures knowledge delivered inside two hours, and those are different skills. Drivers who only practise untimed regularly discover on the day that they are twenty questions behind with thirty minutes left.

The fix is to make your later practice full-length and timed, every time. Eighty questions in two hours, no pausing, no looking anything up. That also builds the concentration stamina that the last twenty questions demand.

Mistake five: answering from experience instead of the rules

This one costs experienced drivers the most. Years of driving in New York teach you what traffic tolerates, and the exam asks what the law requires. On safe driving and customer service questions, the practical answer and the correct answer diverge often.

The fix is a reading habit: ask what the rule requires, not what you would do. If a question offers a convenient option and a strict option, the strict one is usually right.

Mistake six: booking the exam at the end of the window

The 90-day application window is unforgiving, and an exam booked for the final available slot leaves no room for a retake. One bad morning then costs the entire application rather than one attempt.

The fix is scheduling, not studying. Book early enough that a second attempt fits comfortably inside the window. It removes most of the pressure from the first attempt, which usually improves the result anyway.

Mistake seven: leaving questions unanswered

There is no benefit to a blank answer on a multiple-choice exam. Every unanswered question is a guaranteed zero where a guess would have had a chance.

The fix is a rule you apply mechanically: if you cannot see a route to the answer in about a minute, pick the best option, flag it, move on, and come back if time allows. Never leave the screen without an answer selected.

Mistake eight: practising in the wrong language

If you intend to sit the exam in Spanish or Bengali but practise in English, you are adding a translation step under time pressure, and technical vocabulary is exactly where that step breaks.

The fix is simple: choose your exam language at the start of your preparation, not the end, and practise in it throughout.

• Lead with questions; read to fill gaps the questions expose.
• Review guesses as well as errors.
• Spend time on your weakest two categories, not your favourite.
• Make later practice full-length and timed.
• Answer what the rule requires, not what you would do.
• Book the exam early in your 90-day window.
• Never leave a question unanswered.
• Practise in the language you will be tested in.
