12 mistakes that cost candidates marks on the DHA exam

Short answer: The most common mistakes are memorising answers instead of principles, skipping explanations, ignoring weak domains, never practising under time pressure, and changing correct answers out of anxiety. Each is easy to fix with a short, consistent routine.

Preparation mistakes

These happen weeks before the exam, which is good news because you can still fix them.

  1. Memorising answers instead of understanding why they are right.
  2. Skipping the explanation when you answered correctly. You may have guessed.
  3. Studying only your favourite topics.
  4. Relying on one source of questions.
  5. Leaving calculations until the last week.
  6. Starting mock exams too late to learn from them.

Exam-day mistakes

Pressure changes how we read, so build habits that protect you.

  1. Spending too long on one question instead of flagging it.
  2. Not reading the last line of the stem before the options.
  3. Missing words like "first", "best" or "most appropriate".
  4. Changing answers without a clear reason.
  5. Forgetting to check the clock at the halfway point.
  6. Leaving questions unanswered at the end.

A short fix list

Keep a notebook of "rules" from missed questions. Do one timed set a week. Review flagged questions before every mock. And practise with the same on-screen tools you will use in the exam, such as flagging and striking out options.
