No, it is just a myth that coaching is required to crack the exam. Self-study is also enough for the preparation. But the real difference that coaching institutes bring is boosting your preparation with proper mentorship. A good teacher knows how to put your efforts in the right direction and get the maximum result with minimum efforts. Also, the study material provided by the coaching institutes saves the time you’ll usually spend taking notes. When the syllabus that you have to cover is as extensive as the UPSC’s, every minute is precious. So, enrolling in a coaching institute can cut that extra work from your routine and you can solely focus on your ultimate aim.
