I highly recommend the Zoffness College Prep course. My son, who is currently a senior in high school, increased his ACT scores with Ben's help, and his grades kept improving after every test. Ben is truly a great help for any student that is looking to succeed with SAT/ACT testing. My son always came home talking about how great the class was, and how it was so informative. Ben always used simple, but efficient explanations to solve problems and make students improve. The course was very well organized, as it shows a clear progression in material, and the practice tests really help the students. I highly recommend this program, and I would urge others to enroll in the program because there is a guarantee that the test grades will go up with Ben.
