Introduction:
When preparing for a competitive exam like UPSC, it is crucial to allocate time effectively to different types of questions. Case-based questions and theory-based questions both play an important role in the exam, and it is essential to have a balanced approach to studying for them.

Allocation of Time:
To decide how much time to allocate for case-based questions versus theory-based questions, it is necessary to consider the following factors:

1. Exam Pattern: Analyze the past year's question papers and understand the weightage given to case-based and theory-based questions. This will provide insights into the exam pattern and help determine the appropriate allocation of time.

2. Subject Understanding: Evaluate your strengths and weaknesses in different subjects. If you have a strong theoretical foundation in a particular subject, you may require less time for theory-based questions and vice versa.

3. Difficulty Level: Consider the difficulty level of case-based and theory-based questions. If case-based questions are more complex and time-consuming, you may need to allocate more time for them.

4. Practice: Case-based questions often require critical thinking, problem-solving skills, and application of theoretical knowledge. Allocating sufficient time for practicing such questions will enhance your ability to analyze and answer them effectively.

5. Time Management: Set realistic goals and create a study plan that allows you to allocate enough time for both types of questions. Prioritize topics based on their importance and allocate more time accordingly.

Conclusion:
In conclusion, the allocation of time for answering case-based questions versus theory-based questions should be based on the exam pattern, subject understanding, difficulty level, practice requirements, and effective time management. Striking a balance between the two types of questions will ensure comprehensive preparation and increase the chances of success in the UPSC exam.
