Yes, based on available information, you are likely eligible for the Karnataka Administrative Service (KAS) Exam even though you completed your Bachelor of Arts (BA) degree online from Sikkim Manipal University in 2023.

The Karnataka Public Service Commission (KPSC), which conducts the KAS exam, typically requires a candidate to possess a Bachelor's degree from a recognized university.

The KAS notification usually doesn't differentiate between online and regular degrees as long as the university is recognized.
