In page Amateur radio licence categories in India:

"

To obtain a licence in the first four categories, candidates had to pass the Amateur Station Operator's Certificate examination.[1] This examination is held monthly in Delhi, Mumbai, Kolkata and Chennai, every two months in Ahmedabad, Nagpur and Hyderabad, and every four months in some smaller cities.[2] The examination consists of two 50-mark written sections: Radio theory and practice, Regulations; and a practical test consisting of a demonstration of Morse code proficiency in both sending and receiving.[3] After passing the examination, the candidate must then clear Local Police and Central Home Department verification. After clearance, the WPC grants the licence along with the user-chosen call sign (if available). This procedure on an average takes 12 months.[4]
