You knew the physics. You did the maths right. Then the answer key says (c), you marked (a), and only on the way home do you notice the word NOT in the question. Reading slips like this follow patterns, and a small, fixed habit catches them. Here it is, with a worked example and a one-week plan.
Why do you misread questions you know how to answer?
Under time pressure you read for the gist and fill in the rest from what you expect. That fails on the few words that flip the meaning.
The decision researcher Shane Frederick built a short test around this tendency. His Cognitive Reflection Test (Journal of Economic Perspectives, 2005) measures "the ability or disposition to reflect on a question and resist reporting the first response that comes to mind."
Negative wording is the clearest trap. Neville Chiavaroli's review, Negatively-Worded Multiple Choice Questions: An Avoidable Threat to Validity (2017), notes that item analysis of high-stakes exams often shows otherwise high-performing students picking the wrong option on NOT-type questions. It adds that highlighting the negative term does not prevent this, because evidence suggests many students answer as if the question were positively phrased. So underlining NOT is a start, not a fix. You also need a step that forces you to use what you marked.
Units are the other classic slip, and not only for students. NASA's investigation board found that the 1999 Mars Climate Orbiter was lost because of a failed translation of English units into metric units in ground-based navigation software. If a spacecraft team can miss a unit, so can you late in a three-hour paper.
How do you stop misreading questions in exams?
Use the same five steps on every question.
Read once for the story. What is happening: a car, a reaction, a graph? Do not solve yet.
Underline what is asked. The exact quantity or choice: "time taken", "magnitude of the force", "the incorrect statement".
Circle every unit. The units you are given and the unit the answer must be in: km/h against m/s, mL against L, cm against m.
Box the flip words. NOT, EXCEPT, INCORRECT, LEAST, only, both, approximately, magnitude.
Say the task in your own words, under your breath. "I need the false statement, and speeds are in m/s." This is the step that makes your pen marks count.
For any NOT or EXCEPT question, add one more move: write T or F next to every option, then choose the single F.
What does the habit look like on a real question?
Try this one: "A car starts from rest and accelerates uniformly to 72 km/h in 10 s. Which of the following is NOT correct? (a) Its acceleration is 2 m/s². (b) It covers 100 m. (c) Its average speed is 20 m/s. (d) Its final speed is 20 m/s."
Underline: "NOT correct". You want the false statement.
Circle: 72 km/h given, m/s in the options. Convert first: 72 km/h is 20 m/s.
Box: NOT.
Say it: "Find the false one, working in m/s."
Now mark each option. Acceleration is 20 ÷ 10 = 2 m/s², so (a) is T. Distance is ½ × 2 × 10² = 100 m, so (b) is T. Average speed for uniform acceleration from rest is (0 + 20) ÷ 2 = 10 m/s, so (c) is F. Final speed is 20 m/s, so (d) is T. The answer is (c).
Notice the two ways to lose this mark without any physics error: skip the conversion and get 7.2 for the acceleration, or miss NOT and tick the first true statement, (a).
If you get an answer wrong and cannot see whether the slip was in the reading or in the method, the Fermi Problem Library has worked problems with a step-by-step solver that explains the reasoning, so you can find the exact step where you went off track.
How do you make the habit automatic before the exam?
Build it in practice, not on exam day.
Days 1-2: Use all five steps on every practice question, even easy ones. Slow is normal.
Days 3-5: Keep the pen marks, but say the task silently.
Days 6-7: Take a timed mock. Afterwards, sort every wrong answer into one of three piles: did not know, method error, reading slip.
The reading-slip pile tells you which of the five steps you skipped. Repeat the week focusing on that step.
Parents can help without adding pressure. After a mock, try: "Which of these did you actually know how to do?" rather than "Why did you get this wrong?" If worry about exams is affecting sleep or mood, talk to a school counsellor or call Tele MANAS on 14416.
If you are not sure which topics to practise the habit on, Fermi's AI tutor works out what you already know and builds a plan for the session, so you start with the questions that matter.
