Due to my position (Human Resources Director) in an American multinational company located in Bogota, Colombia, and having studied English in the United Kingdom, I decided it was time to study for an MBA in order to further my career. I needed 250 on the CBT Toefl. I was advised to attend the best and most expensive prep center, Kaplan Bogota, so I did. I took the TOEFL twice. The first time I scored 207 and the second time 190, very far from the score I needed for my MBA. Seriously, I don't know how could somebody claim to have scored 290 with Kaplan preparation, and even less with this Kaplan TOEFL book that I recently disposed in the garbage. Moreover checking the ETS's statistics for the last 3 years and the standard deviation for Toefl scores, no one has scored above 287. Therefore I find very dubious some reports stated herein. Use common sense and never enroll in a Kaplan course.
