The Princeton Review is an education services company providing tutoring, test preparation and admission resources for students. It was founded in 1981. and since that time has worked with over 400 million students.
I used this publication a while ago, and it was quite helpful. It provided fundamental information related to these exams with examples and illustrations. Common tips for satisfactory performance were also incorporated into this publication, and I think it can aid a number of people who were hoping to crack it and reduce the difficulty. Personally for me, it was quite applicable. Overall, it was a worthwhile publication.
