1) Prof was not there at office hour and did not tell student 2) terrible assignment, could tell by many spelling mistakes n do not properly lay out questions so students miss answering stuffs 3) inconsistency in marking throughout tutor and professor does not care (ie tutors never discuss marking together to ensure consistency) 4) terrible teaching, never have proper example in class 5) clearly he is teaching a mix of economic with accounting subject but he is not in that field
