What will be the exam pattern for under graduate and post graduate?
The ICAR AIEEA Ug and Pg entrance exam is conducted by the National testing agency on the behalf of icar board the syllabus of this exam is varied stream to stream.
The best institutes or universities in India to study agriculture science Bsc./MSc./Phd are mainly Banaras Hindu University (BHU) Varanasi, Uttar Pradesh, G. B. Pant University of Agriculture and Technology, Pantnagar, Uttarakhand, and Chaudhary Charan Singh Haryana Agricultural University, Hisar, Haryana.
if you want to get admission in these universities than its compulsory to appear in the ICAR exam that's conducted by NTA every year and if you belong to the state in which university is located you can appear in its state agriculture entrance test exam
if you want to know how to prepare or how to crack the icar ug exam you view my post.
best of luck...
