Not possible in Hindi medium
There are certain constraints that make it difficult to prepare for the UPSC exam in Hindi medium. Let's delve into the reasons why it might not be feasible:

Lack of resources
- The availability of quality study material and resources in Hindi medium is limited compared to English medium.
- Many coaching institutes predominantly offer courses in English, making it challenging for Hindi medium students to access the same level of guidance and support.

Complexity of the exam
- The UPSC exam is known for its vast syllabus and intricate questions that require a comprehensive understanding of concepts.
- Translating complex topics from English to Hindi may not always convey the exact meaning, leading to misunderstandings and confusion during the exam.

Competitive environment
- The competition in the UPSC exam is fierce, with lakhs of aspirants vying for a limited number of vacancies.
- English medium students tend to have an edge due to their exposure to a wider range of study material and resources.

Language proficiency
- While the UPSC allows candidates to choose Hindi as a medium for answering the exam, proficiency in English is essential for the preliminary exam.
- English comprehension and communication skills play a crucial role in the interview stage of the UPSC exam.
In conclusion, while it is not impossible to crack the UPSC exam in Hindi medium, aspirants may face several challenges due to the lack of resources, the complexity of the exam, the competitive environment, and the importance of English proficiency. It is advisable for Hindi medium students to supplement their preparation with English language skills to enhance their chances of success in the UPSC exam.
