Generally, the UPSC requires a Bachelor's degree from a recognized university. While they usually don't specifically exclude distance learning degrees, it's crucial to check the official UPSC notification for the year you intend to apply. The notification will clearly state the acceptable types of degrees and any specific requirements.
Key things to verify in the official UPSC notification:
* Recognition of the University: Ensure your distance learning BSc degree is from a university recognized by the UPSC or the Association of Indian Universities (AIU).
* Minimum Percentage: Check the minimum percentage of marks required in your degree.
* Graduation Completion: Confirm the date by which you must have completed your degree. You need to meet the eligibility criteria *before* the exam date, not just be enrolled.
In short: While a distance learning BSc *might* be acceptable, don't assume it is. Always refer to the official UPSC notification for the specific year you plan to take the exam. Their website is the only definitive source of information.
