So many people from Houston have been asking me whether Princeton Review or Testmasters is a better SAT prep program. Honestly I have taken both and testmasters' s program is much more organized and easy to understand. Their tips and tricks really stick with you, and the teachers are funny and knowledgeable. They're all younger so they get along with the students really well. Testmasters also has an option to buy where you come in on the weekends and take ANY sat or act ever written. You can take as many as you want in the 4 hour span you are given. Testmasters also gives you a $25 dollar discount if you use the code: CV061. I recommend their program over any one else's because your score WILL increase once you finish the course.
