Louisville Test Prep is a teaching and test preparation service. While we make every effort to accommodate everyone's needs and improve everyone's score(s), there are several factors that play a role in determining scores, including but not limited to, aptitude, previous scores, experience, grade point average, and attitude. Much as we would like to, we cannot guarantee results. We can, however, give you a very good idea (based on the information you provide) as to how we can reasonably expect to improve your score.
