Agricultural and Biosystems Engineers Licensure Examination syllabus

PRC Annex A organizes the ABE licensure examination as three papers: Power, Energy and Machinery Engineering and allied subjects at 32 percent; Land and Water Resources Engineering and allied subjects at 32 percent; and Structures, Environment Engineering, Bioprocess Engineering and allied subjects at 36 percent. The earlier eight-domain weights are nested only inside those paper groups.
