Turn by turn is what "the book" and it's handful of reference examples before the actual test questions are supposed to be about. The classroom time is for general theory and the QnA part for debugging errors in the understanding of students. (In High School I found it way more useful to spend most of the in-class time doing homework... even if for another class.)
