Coaching can significantly impact the success rate of UPSC candidates by providing structured learning, expert guidance, and essential resources. Coaches can demystify the syllabus and can help in prioritizing topics based on their weightage in exams. Furthermore, coaching institutes offer extensive preparation materials, including notes, mock tests, and insights on exam patterns. However, reliance solely on coaching can be detrimental; self-study and consistent effort are essential to internalize concepts. Ultimately, coaching can be beneficial, acting as a supplement to individual learning needs and enhancing overall preparation.
