You are required to write two midterm essays that are two pages long. My advice on this is work on it for a long time do not do it three or four days before it's due. Next make sure you follow all of the rules and procedures he requires for the essays because if you do not it can knock points off of your grade. Also make sure you read over what you wrote and make sure it meets all requirement and goes with the topic he has given you. He will also give you essays or "Open Responses" on every unit exam. My advice for that is do not sugar coat your answer and just answer the question that is all he looks for. Honestly the essays on the test are usually easy you should just study for big topics because that is usually what is on the essays
