Dear Vignesh, once you appear in ICAR AIEEA and you qualify, you need to register on the official website for admission through counselling. Only those candidates who have qualified in the exam can attend the counselling. You need to download the call letter to attend counselling. Now, lets say you cleared ICAR and you have secured an admission in one of their institutions, for the next 4-5 years, you will be studying subjects like Agronomy, Agricultural Biochemistry, Agricultural Economy, Biotechnology and Agricultural Metereology amongst many others. Later, you can either continue your research or you can start working in various private and public sectors.
