Hi Diana Rongpipi !

In order to study B.Tech agricultural engineering in colleges under ICAR exam you have to appear the exam in PCM(not PCB/ACB) which is mandatory for other B.Tech courses also(i.e b.tech dairy tech , b.tech biotech and b.tech food tech)

According to the previous year cutoff :-

BHU the cutoff is expected of 485+

CCAU the cutoff is expected of 465+

GBPAU the cutoff is expected 455+ and the minimum cutoff is expected of 243 marks in icar exam

However, the competent authority, ICAR, may provide the relaxation in ICAR cut off marks, in case the required numbers of candidates to be called for counselling is not available.

General and UPS category candidates must secure the minimum of 50% cut off in order to qualify. While, that for SC/ST/PC categories, it is 40%.
