1. Incomplete lecture slides with poor explanations 2. Tests are too heavily based on definitions and terms. There is no actual learning here. Marks reflect this poor method of testing. Providing rationale answers are considered incorrect and punished even if it is applicable to the real world. This shows laziness on the instructor's side. 3. Professors do not listen to explanations or reason 4. Say that tests are bell curved but give no proof or amount by how much. I have found documents from Summer 2010 test 2 marks and those marks were also 'bell-curved' 5. Give unclear instructions when asking for help
