As long as I get the gist from outlines and class discussions, I'll be fine. I'll join a study group for extra insurance. Legal writing will teach me how to write in lawyer talk. I'll learn lots of Latin phrases and write in a way no one will understand, except for fellow lawyers. Practicing exam taking is a waste of time.
Professors never ask the same question twice.
Law school is not like undergraduate study. You will not be quizzed regularly. You will not feel good about any one class.
