Preparing for UPSC while also studying for your graduation can be challenging, but with proper planning and dedication, it is definitely possible to manage both. Here is a detailed guide to help you get started:

1. Understanding the UPSC Exam:

- The Mains examination is subjective and includes essay writing, general studies papers, and optional subjects.
- The Interview stage assesses your personality, communication skills, and knowledge.

2. Choosing Optional Subjects:
- UPSC allows you to choose one optional subject for the Mains examination.
- Select a subject that you are genuinely interested in and have a good understanding of.
- Some popular optional subjects include History, Geography, Public Administration, Sociology, etc.
- Research about the syllabus and previous year question papers to make an informed choice.

3. Understanding the Syllabus:
- The UPSC syllabus is vast and covers various subjects like History, Geography, Polity, Economy, Science, and Technology, etc.
- Read the syllabus thoroughly and make a study plan accordingly.
- Divide your time between UPSC preparation and graduation subjects, giving more time to the subjects that require more attention.

4. Prioritizing your Preparation:
- Start by focusing on the basics of each subject and gradually move towards advanced topics.
- Develop a habit of reading newspapers and magazines to stay updated with current affairs.
- Make short notes while studying to revise the topics easily.
- Solve previous year question papers to understand the exam pattern and identify your weak areas.

5. Time Management:
- Create a timetable that allocates specific time slots for UPSC preparation and graduation studies.
- Prioritize your tasks and ensure that you have dedicated time for both.
- Make efficient use of your breaks and spare time to revise or read.

6. Seek Guidance:
