WaveLength is an excellent prep course for the SAT. Before I knew about this course, I had a private tutor, who helped our son get a very competitive score, but it was not as high as he wanted. I heard about WaveLength from a couple of friends, one whose son got a 34 on the ACT. My son was a little reluctant at first, but Matt and Marlee convinced him to try another approach and get this done! I cannot say enough about this course. If the student works hard and follows their tips he or she should see positive results. A++++!!!!!!!!!
