Yes, a 12th pass individual can apply for the UPSC (Union Public Service Commission) exam, but they must meet certain eligibility criteria. The minimum educational qualification required to apply for the UPSC Civil Services Exam is a bachelor’s degree from a recognized university. So, while a 12th pass can start preparing for the exam, they would need to complete their bachelor’s degree before they can appear for the UPSC exam.
After completing the 12th grade, you are ineligible to sit for the UPSC exam. This is because the minimum qualification necessary to apply for the UPSC exam is a graduation from a recognized university. However, you can commence your preparation immediately after completing your 12th board exams.
