i want to become DC i am from assam should i apply for apsc or upsc
You will have to give UPSC CSE examination to become DC.
After clearing APSC you can get these post:
DSP, Excise Officer, Food Department officer, SDM and Class Tehshildar.
But to become a DC you will have to appear for Civil Services Exam and then you will have to get a rank under 100.
All the best!!
