Both my son (a college sophomore) and daughter (a high school senior) utilized Ben Zoffness for tutoring assistance with the math section of the ACT. Both saw their performance over multiple practice tests improve as Ben helped them zero in on the types of problems that were giving them trouble and gave them great guidance for solving those problems and handling the test in general. They each ended up having to take the ACT only once. We found Ben to be a consummate professional and a huge help. I highly recommend him and his company.
