There are typically between 4 and 6 Fixed Exchanges on every SAT.  That said, there were 9 of them on a recent SAT ~ representing 100 points in the Math Section of the SAT.  Very common on the ACT also.  You can create significant opportunities for score improvement in the Math Section by learning how to work the Fixed Exchange problems.  As with all of the other problems, our approach standardizes the work associated with this problem type ~ allowing you to work all of the problems in this category with 4th grade math skills in lieu of Algebra.  Safe to say , if you can not confidently work the problem in less than 90 seconds with 4th grade math skills, then you need our program.
