This situation is highly unlikely to arise as the questions have been meticulously created and vetted by experts. However in this scenario, the student can make a note of the question and email the IMC team at support@international-maths-challenge.com after the test. Note that the timer cannot be paused for this reason. A suspected incorrect question by the student cannot be treated as a technical issue. The student will have to note down the question and continue with the test. Once student submits the question, the IMC team will get back in 2 business days on the decision. Note that till date, no question has been found faulty in the IMC exams.
