The questions are great assessment of the material...no tricky or confusing questions not addressed in the test. You have to know the material and understand it to do well. It is not a pure regurgitation of material. The answers are in the Teacher Guide...so if you had time on your hands you could just look in the TG and create your own tests/quizzes and skip the extra purchase. I like that they have points assigned to each question to make it easier to score.
