My Con Law professor allows students to take practice exams and review answers with him to prepare for the final. He has only one old exam available to students for practice. However, several other Con Law professors at my school have at least 3-4 exams available. In preparation for finals, I would like to practice taking my professor's old exam and, for experience and evaluation purposes, would like to take at least one exam.
Can I ask the professor to come up with an additional fact pattern? Should I use the other professors' exams?
