Agriculture All India Entrance Exam - AIEEA (ICAR)

Tips, Tricks

1. who to prepare icar plz tel me book name ug plz sir
2. i want to join icar and i am coming from General category. but major problem is 60% mark with first devesion whereas sc and st its 50% only why? its a harmful think for General studends. i think like this icar can not improve his quality. if any region student can't obtained 60% who is guilty University or student. we know very well that many University in india under curuption. and it is take money from student far high percent. so if poor student can't pay University discrease his percent. pls change it for illegible student. i think it should 50% for General and 45% for sc or st category.
3. may i know how to prepare for icar aieea entrence exams. is there any inatitutes, books, etc...
