SAT Tutor Certification

I am teaching an upcoming SAT Workshop in the Orlando, FL area using the College Board's new SAT Study Guide materials.  I contacted the College Board to see if there was any type of certification I could go through from them.  They said no, but suggested contacting Khan Academy.  By chance, does Khan Academy possibly have or would they be interested in offering a certification process?  

In preparing for my workshop, I did find an error in the new SAT study guide on pg. 553 question #20 in the solutions section.  In the book, it is written that 10/30 x 2400 = 80 which is incorrect.  It would equal 800.  They also printed 10/30 x 3300 = 110 which is also incorrect.  It would equal 1100.  

If anyone knows of a reputable certification program that I could go through, I would certainly appreciate it.  

Thank you,
