Mary, looks like you have a good structure in place. One other consideration are those students with some level of learning disorder. Not all students think alike and for some students they struggle to translate their knowledge onto various forms of exams. For some they may invert ideas and concepts which can result in selecting wrong answers even when they know the correct answer. For others they may struggle to put their thoughts in writing for essay type questions. The more you get to know each of your students the better prepared you will be in identifying which of your students study but may have difficulties still with exams. James Jackson
