Which of the following is a disadvantage of not following exam instructions?

Not following exam instructions can lead to a waste of time on irrelevant tasks. When students ignore the guidelines set forth for an exam, they may spend time working on questions or sections that are not relevant to the material being tested, or they might approach the exam in a way that diverts from what is expected. This misallocation of time can ultimately affect their overall performance negatively, as they may not complete the essential parts of the exam or may misinterpret what is required, leading to lower scores.

In contrast, the other options suggest outcomes that are either beneficial or not typically associated with failing to adhere to exam instructions. Improved performance and teamwork during exams are generally connected to understanding and following those instructions, while creativity in answering is not necessarily a positive outcome in a structured testing environment where specific responses are expected.
