For 80 years, Kaplan Test Prep has been helping students grow their knowledge, skills and confidence so they can be their best on Test Day. Our prep books and online resources provide the expert guidance that students need at every step of their educational journey – incorporating years of test-specific data and strategies tested by Kaplan students and our own expert psychometricians.

After helping millions of students, we know what works. Our guides deliver knowledge with clarity and simplicity while focusing on the specialized strategies that keep test-takers ahead of the clock and at the top of their game.

We offer preparation for more than 90 standardized tests – including entrance exams for secondary school, college, and graduate school, as well as professional licensing exams for attorneys, physicians, and nurses.

With a full array of self-paced and live online courses, as well as print books and mobile apps, you can use Kaplan to study on your own schedule and at your own speed. Kaplan’s private tutors and admissions consultants supplement those offerings with one-on-one support.
