Query: Waste of money !

Books written by the company that write the tests are worthless. Trust me....I read bad reviews on these books prior to purchasing them and bought them anyway. Once I got them, I soon realized they were of no help in preparing me study for the Praxis Exams. Barron's provides the best source of materials for study for the Praxis Exams. Do not waste your money on these books.
