The best answer is that, it depends. For example, I am in the winter quarter of my first year and I have 2 midterms next week followed by 2 more midterms the following week (all for four different classes) and then a week free of exams followed by a week with 2 finals (1 class but first exam is written and second exam is a practical) and then 4 finals the following week. Most are multiple choice tests (at least all that I’ve had so far), some are quizzes, and, depending on the class, there may be group projects. It’s basically exactly what you’d expect of a graduate program.
