There might be a misunderstanding regarding the category "SC+ESM" on your SSC CPO 2024 admit card.

The "ESM" (Ex-Servicemen) category is typically for candidates who served in the Indian Armed Forces and are now retired . Since you are currently serving in the BSF, which is indeed an armed force, you wouldn't fall under the ESM category.

The "SC" likely refers to the Scheduled Caste category, which is a reservation category for candidates belonging to specific communities in India.

It's best to directly contact the Staff Selection Commission (SSC)  that conducts the CPO exam. They can clarify the reason behind the "SC+ESM" category on your admit card and guide you further.

There might be a technical error in the system that led to this combination being displayed. In some cases, the admit card might show both the reservation category (SC) and a separate "ESM" section even if it doesn't apply to you. This could be for informational purposes.

If the exam date hasn't passed yet, you can take the exam as scheduled. During the exam, the category selection wouldn't affect your performance. After the exam, contact the SSC CPO to understand the reason behind the "SC+ESM" category and ensure your application is categorized correctly for evaluation.
