I have two other tutoring firms before I had my kids begin with Quest Advanced Learning. As a mother of three, it was difficult to take them to centers in one instance or to keep on the toes of inexperienced tutors. When we started with Quest, they sent us an amazing tutor that not only helped my daughter with her rigorous high school curriculum; however, they helped by boys do extremely well on the SATs when the advisors told us that they would not be able to get the scores. They were professional and kept in contact with the teachers and us. The tutor was certified and is now like part of the family. They are worth every penny. They are not the cheapest, but they are not the most expensive as well. You get what you pay for. Don't look anywherelse for any reason.
