In the Mathematics optional paper of the UPSC exam, it is not necessary to attempt all the questions. The number of questions to be attempted depends on various factors, such as the difficulty level of the questions, the time available, and the candidate's proficiency in the subject. It is important to strategize and prioritize the questions based on these factors.


There are several factors to consider when deciding which questions to attempt in the Mathematics optional paper:

1. Difficulty Level: Some questions may be more challenging than others. It is advisable to attempt the questions that seem familiar and solvable within a reasonable amount of time.

2. Time Management: The Mathematics optional paper has a limited time duration. It is crucial to allocate time wisely among the questions. Spending too much time on a single question may result in insufficient time for other questions.

3. Strengths and Weaknesses: Every candidate has their own strengths and weaknesses in mathematics. It is recommended to prioritize the questions that align with one's strengths to maximize the chances of scoring well.

4. Mark Distribution: It is important to analyze the mark distribution of the paper. Some questions may carry more marks than others. Prioritizing higher-mark questions can help in maximizing the overall score.

2. Solve High-Mark Questions: Identify and attempt questions that carry higher marks. These questions contribute significantly to the overall score and should be given priority.

3. Skip Difficult Questions: If a particular question seems too challenging or time-consuming, it is advisable to skip it initially and come back to it later if time permits. This ensures that easier questions are not left unattempted due to time constraints.

4. Double-Check Answers: After attempting all the questions, it is crucial to review and double-check the answers. This helps in minimizing errors and improving accuracy.


In conclusion, it is not necessary to attempt all the questions in the Mathematics optional paper of the UPSC exam. Candidates should strategically choose the questions based on factors such as difficulty level, time management, strengths and weaknesses, and mark distribution. By following effective strategies and prioritizing the questions, candidates can optimize their performance and increase their chances of scoring well in the examination.
