His geography classes are mainly self-directed learning. Try your best and you’ll be ok. Take notes on the textbook materials because some of the concepts will not be covered in class, but will still appear on the tests. With the written assignments, it’s better to over-analyze than to under-analyze your arguments. He might miss out on a few sentences while reading your paragraphs and deduct points for “not answering the question”, so it’s ok to be a bit repetitive in your writing. As for the unit tests, they are usually a jigsaw of long and short responses with argumentative prompts. The best way to prepare for them is to preplan some arguments supported by the facts and concepts covered during class. Invest in some good pencil crayons because you cannot colour the maps with markers or pens (very unprofessional) and you will get points deducted for it.
