Why OAT Bootcamp Offers The Best Prep Course

OAT Bootcamp gets our top grade because, frankly, they just do everything incredibly well. Here’s a quick break down of how this course works. From a high-level point of view, OAT Bootcamp is effectively a massive collection of OAT study materials.

They offer video lessons, written study notes, work sheets, question banks, full-length tests, subject-specific tests, strategy guides, and a few other features. Organizationally, it’s all grouped by subjects tested on the OAT: Biology, General Chemistry, Organic Chemistry, Reading Comprehension, Physics, and Quantitative Reasoning.

Thus, you essentially have subject-based learning modules where all of the different study materials are bucketed. For example, under the Biology module, there are Biology-related Practice Tests, Question Banks, Quiz Questions, Video Lessons, Notes, Flashcards and Strategy Guides.

In other words, you’ve got a bunch of study content, all categorized out based on tested subjects (except for the full-length practice tests as those touch on all topics). Then, overarching everything in the course is the study schedule. This is a critical part of the program.

OAT Bootcamp gives you a PDF study schedule that guides you through all of the study materials in a very specific order. It gets very granular by providing a day-by-day breakdown of exactly what you need to be completing and when.

To summarize, you follow this checklist-style study schedule and work your way through all of the study material in the course over 10 weeks or so.

An average day can take anywhere from 2.5 to 6 hours depending on how quickly you move and what you’re learning. That’s more or less how it works. You take it day-by-day, and work your way through all of the material and practice work, with the schedule being pretty back-weighted for full-length practice tests.

In terms of the highlight reel, there are four big reasons we recommend using the Bootcamp course. The first reason is the practice material. It is highly realistic of what you’ll see on test day in terms of question difficulty, content, and structure. It’s close to (if not the) best in the space.

Plus, Bootcamp also provides more practice work than just about every other program with around 8,800 practice problems and 10 full-length practice tests, so it’s a really strong program for practice-oriented learners

The second highlight is their video content. OAT Bootcamp has really good content-based video lectures, and the video-based solutions to problems are incredibly helpful.

Then third, their chemistry material must be called out. If you struggle with chemistry, you have to go with OAT Bootcamp. Chemistry is kind of their specialty, and their lead chemistry instructor, Dr. Mike, is fantastic.

Then the final benefit of using Bootcamp is cost. The primary OAT Bootcamp study package costs $500, which isn’t necessarily the cheapest course in the space. However, it is a very solid value. It costs a few hundred dollars less than Kaplan’s course, and it’s pretty reasonable given all of the material and support they provide.

Plus, I would just note that despite the pretty approachable price point, Bootcamp still frequently run sales and special promotions, and a lot of times you can find their course on sale, so make sure to check for coupon codes. You can usually save around 10% on the Bootcamp package.

Why Kaplan Is A Great OAT Prep Option

Kaplan’s OAT prep program is likely the most comprehensive and material intensive course we’ve reviewed. Here’s how the course works.

The Kaplan OAT study materials are broken out into different “courses” for each of the six subjects tested on the exam. This is the same as the other two companies on this list. They all structure their materials by subject. However, here’s where Kaplan differs.

Within each subject-based course, Kaplan has a number of modules to complete. Some courses have only a couple of modules, while others (like Biology) have close to ten. In any event, each module is comprised of a number of assignments and different types of study material.

Just about every module starts by having you read a chapter from the Kaplan e-book, and from there, there is a mix of tasks. You watch video lessons, work quizzes of varying difficulty, read through “ReKaps” (quick and simple explainers like condensed notes), and sometimes even review 3D models.

It’s a very diverse mix of assignments in each module. However, that’s just the self-paced materials. Near the middle-to-end of the course, you’ll start taking full-length mock exams. Those are back-weighted as you get closer to exam day.

Now, if that all sounds like a lot, it’s because it is. Kaplan is very material and time intensive. If you’re going to absolutely immerse yourself in prep, Kaplan has more material than OAT Bootcamp.

The clear highlight of Kaplan’s program though is their live classes, which is something Bootcamp does not offer. If you’re the type of student who thrives on live classes—whether it’s because you prefer the structure and guidance or need the accountability of a set schedule to stay on track—Kaplan is the clear choice.

Over the course of 15 expertly crafted 2.5-hour sessions, Kaplan provides a step-by-step breakdown of everything you need to know for the exam.

Their instructors are not only highly knowledgeable but also excellent communicators, making complex topics easier to understand. The lesson plans are thoughtfully designed and highly efficient, blending content review, exam strategy, and guided practice seamlessly.

After each class, you’ll receive targeted assignments that align directly with what was covered in the session, reinforcing key concepts and strategies.

This structured approach gives Kaplan’s live online program a more traditional college course feel compared to the self-driven nature of Bootcamp’s program, making it ideal for students who value a guided, hands-on learning experience.

Basically, at $1,500+ for their live online course, Kaplan is more expensive than Bootcamp, but they also give you a lot more material and the live classes add a ton of value.
