Apply yourself and work with Dr. Baker. If you do so, your grade will come naturally. Come to class prepared. Go to class everyday with the reading and homework completed. Always look at the big picture in class.
Exams are straight forward without any tricks.
Understand the logic, don't memorize. Keep yourself motivated and stay with the class. Take Dr. Baker's hints seriously. He doesn't waste your time or his telling you things that you don't need to know. If you listen carefully, you will find he spells out his expectations and plans in details.
