Hello

If you want to become an IAS officer, you can choose any group CEC, MPC, or BiPC as IAS does not require a specific subject stream.
However, many students prefer CEC (Commerce, Economics, Civics) or MPC (Maths, Physics, Chemistry) because they help build analytical and general knowledge skills useful for the IAS exam.
CEC helps with subjects like economics and polity, which are important for the IAS syllabus.
MPC develops problem-solving skills and logical thinking, also useful for the exam. BiPC (Biology group) is less common for IAS aspirants, but still possible if you prefer life sciences.
