One of the most common mistakes made during IAS exams is underestimating the importance of mock tests. A good mock test can help you identify your weak areas and work on them accordingly. Another mistake that students often make is not reading the question properly. Many students tend to hurry through the questions and end up making silly mistakes. So it's important to read each question carefully and understand what is being asked before trying to answer it. Lastly, many students lose focus during the exam and start thinking about things other than the questions at hand. This can lead to careless mistakes. It's important to stay calm and focused during the exam so that you can attempt all the questions correctly.
