Introduction:
When it comes to attempting questions, students often find themselves torn between attempting all the questions or focusing on quality over quantity. While both approaches have their merits, it is generally advisable to prioritize quality over quantity. In this response, we will delve into the reasons behind this recommendation and provide a detailed explanation.

Quality over Quantity:
Focusing on quality over quantity when attempting questions offers several advantages:

1. Depth of Understanding:
By prioritizing quality, students can delve deeper into the concepts and gain a thorough understanding of the subject matter. This approach allows for a comprehensive grasp of the topics, enabling students to answer questions accurately and confidently.

2. Application of Knowledge:
Quality-driven attempts facilitate the application of acquired knowledge to solve complex problems. Rather than merely skimming through questions, students can invest their time in analyzing and comprehending the question requirements, thereby applying the relevant concepts effectively.

3. Reduced Errors:
Rushing through questions to attempt all of them often leads to careless mistakes. By focusing on quality, students can minimize errors and maximize accuracy. This attention to detail enhances the overall quality of their responses and increases the likelihood of scoring higher marks.

4. Time Management:
Attempting all questions within the given time frame can be challenging and may result in time mismanagement. Prioritizing quality allows students to spend ample time on each question, ensuring a more thorough and thoughtful response. This approach optimizes time utilization and prevents rushing through questions.

5. Mark Allocation:
In many exams, questions are assigned different marks based on their complexity. By prioritizing quality, students can strategically allocate their time and effort to questions that carry higher marks. This approach maximizes the potential for earning more marks and improves overall performance.

Conclusion:
While attempting all questions may seem tempting, focusing on quality over quantity is undoubtedly the wiser choice. It allows for a deeper understanding, effective application of knowledge, reduced errors, improved time management, and optimized mark allocation. By adopting this approach, students can enhance their performance and increase their chances of achieving better results in UPSC exams.
