My daughter took the SAT course and her score did not improve at all. We were very disappointed and had been hoping for the 200 point increase that they promised. She is an excellent student, attended all but one class (she was sick) and took the practice tests. The teacher did not seem helpful when my daughter said her scores were staying the same. The company has been difficult about honoring their money back guarantee and needed proof of her score before taking the class (this is in their fine print). As she had not taken the test before the class this was not possible. Save your money and take a better class!!!
