hello aspirant,

NO, you cannot take Bsc or B.Tech in Diary Technology course after completing 12th in Biology, chemistry and Physics. This is because to pursue B.Sc/B.tech in Dairy Technology, a candidate is required to pass the higher secondary or 10+2 examination with physics, chemistry and maths as compulsory subjects
