If you want to become an IAS or IPS officer after completing your 12th in PCMC , focus on graduation because the UPSC Civil Services exam requires you to have a bachelor’s degree from a recognized university. You can choose any graduation stream, but many students prefer degrees like Political Science, Public Administration, History, or Sociology because these subjects help build a strong foundation for the UPSC syllabus. it’s not mandatory to pick these; you can also pursue Science, Commerce, or Arts as long as you complete your graduation. Along with your degree, start preparing for the UPSC exam early by reading newspapers, improving your general knowledge, and practicing answer writing. So, after 12th, pick a degree you are comfortable with, and plan your UPSC preparation alongside

Hii,
Yes, even if you have an ECE diploma, you can still become an IAS officer. However, you must graduate from an accredited college in any field in order to apply for the IAS exam (UPSC). A diploma is insufficient on its own.
First, enroll in a degree program such as a B.A., B.Sc., or B.Tech (lateral entry is acceptable). You can then get ready for the IAS exam. Many IAS officers have backgrounds in the arts, sciences, or diploma programs. So don't worry, just finish your graduation first and move on.
