The last section ? Full of fail . I went and re - read all my notes in class , which made sense then and still do now . I read the book section which kinda made sense , but was not presented the same as the prof ( no suprize there . )

Question: Why is the information in the book different to what was presented by your professor ?
Answer: Professors want to confuse us so that less students pass the courseAcademics want to confuse us to make the exams harderProfessors want to make it difficult for us to do well on exams by providing different workMost academics tend to interpret literature differently and therefore present it differently
