I highly recommend Paul and Ivy Masters. My son took both a mock ACT and mock SAT before starting his prep classes. Paul analyzed both scores and helped to determine which would be a better fit overall. The weekly classes, at home prep work and option to take a practice test every Saturday is such a great way to keep the students engaged and encouraged. My son took a practice test 1/2 way through and then one the week before the big day. His score went up 7 points from the 1/2 way mark to the actual ACT!(he saw a 13 point increase from the initial mock test!) ONE and DONE!! Highly recommend Paul and Ivy Masters Learning Center!!
