Limitless Prep by Kaplan™
THE FUTURE OF OAT PREP
Discover a whole new way to prep—with drop-in style classes, brand-new 3D modeling, and an expert-recommended study plan. Your high score has never been closer.†
ENDLESS POSSIBILITIES, ENDLESS POTENTIAL
We pick the very best OAT instructors who know the test inside and out—and know how to keep you engaged for your best results. The best part? With limitless drop-in style classes, you can work with them anywhere you are, at the time that suits you best.
FOCUS ON THE RIGHT THINGS
The OAT covers a lot of ground, including two years of undergraduate science. With 3D modeling and augmented reality, you’ll be mastering content in no time. Plus, we’ll provide an expert-made study plan so you can stay focused on the content you really need to know—instead of stressing over the things you don't.
PRACTICE PAYS OFF
Practice helps your score, but realistic practice makes all the difference. Use the pinpointed quizzes to tackle your highest yield problems. Then find out where you really stand with our full-length, test-like practice tests. Build your confidence with prep that looks and feels like the OAT.

We’ll show you all the tips and tricks to maximizing your performance on questions involving: units and vectors, linear kinematics, fluid statics, enthalpy, entropy, Gibb’s, conservation laws, electrostatics, resistors, capacitors, Ohm’s, Faraday, lensmaker equation, waves, sound, light, real and virtual predictions, harmonic motion, springs, frequency, period, wavelength, electric potential, current, conductance, insulation, rotational motion, torque, gravitational systems, projectiles, and inclined planes.
Reading Comprehension
Ability to Read, Comprehend, and Thoroughly Analyze Scientific Information in Passages
You might already know that prior understanding of the science topics presented in the passages is not a prerequisite to answering the test items. But it sure helps to have 50+ passages (with full question sets) to practice with! Learn the expert-devised strategies to help you read, comprehend, and thoroughly analyze the information. Oh yeah, and get all of your points!
Quantitative Reasoning
