Get your 450 and get on with your life.

450 Formula was created by two OTs who took the NBCOT® exam and built the resource we wish we had.

We combined Miles’ creative, memorable teaching style and mnemonics with Kim’s deep knowledge of the exam and 10+ years of tutoring experience to make difficult OT concepts easier to understand and remember.

We don’t just give you more charts and information to memorize. We teach it in a way that helps it finally click.

450 Formula is a self-paced online video course with pre-recorded lessons you can watch anytime. We do not offer private tutoring or live sessions through 450 Formula.

However, Kim and Miles go live for FREE 1–2 times each month in the OT Exam Prepper Facebook study group.

If you’re looking for tutoring, live study sessions, or additional exam support, you can visit Kim’s website at TMPOT.com.

The content taught inside 450 Formula is based on occupational therapy literature and professional reference materials.

NBCOT® publishes a list of references used in the development of its certification exams. We use references from that list, including OT textbooks, professional literature, and articles, when developing our course content.

We do not rely on Google searches, random websites, or unverified online sources to teach exam content.

Our goal is simple: teach you from the OT literature that supports the concepts you’re expected to understand for the exam.

Absolutely! Universities and OT programs can purchase 450 Formula access for an entire cohort.

Your program director, professor, or university administrator can visit the University Admin section and select the number of student seats and access duration needed for your cohort.

Once purchased, the administrator can add students individually or upload a list of student names and email addresses. Each student will then receive an email with instructions to activate their account and begin using 450 Formula.

You can request an extension directly from your 450 Formula dashboard.

Go to Extension Request, tell us why you need additional access, and submit your request. Our team will review it and your request will either be approved or denied.

If approved, the additional access will be added to your account.

If you're having trouble logging in or accessing your 450 Formula account, please contact us at info@450formula.com.

Our support team will respond as soon as possible, typically within 48 business hours.

Be sure to email us from the email address associated with your account so we can locate your information and help you as quickly as possible.

We wish we could! If there were a magic formula that guaranteed every student a passing score, trust us—we'd give it to you.

But no course or study resource can guarantee that you will pass the NBCOT® exam.

What we can do is give you the tools, lessons, strategies, and support to help you prepare. What happens on exam day ultimately depends on how you learn, retain, and apply that information.

We give you the formula. You still have to do the work.

No. Your 450 Formula purchase is for individual use only, and accounts may not be shared with another person.

We understand how expensive preparing for the NBCOT® exam can become, which is one of the reasons we work hard to keep 450 Formula affordable.

If cost is creating a barrier for you, please reach out to our team. We would much rather have a conversation about your options than have you share an account.

Yes! You can access 450 Formula from your computer, phone, or tablet, making it easier to study wherever it works best for you.

Absolutely. You can watch the videos as many times as you need during your access period.

450 Formula is a great option for repeat test takers.

One of the things we hear most often from students who have previously struggled with the exam is that something finally “clicked” after using 450 Formula.

We teach difficult concepts in a simplified, relatable way so you can move beyond memorizing information and actually understand and apply what you’re learning.

Our students have historically seen an average score increase of approximately 40–60 points!

You don’t have to purchase the entire 450 Formula program.

If you already know exactly where your weaknesses are, we recommend purchasing the individual course(s) for the topics you need rather than purchasing the full bundle.

Don’t study everything. Study what your performance tells you to study.

Your access depends on the enrollment plan you purchase. When you enroll, you’ll see the available access options and the length of access included with each plan. Choose the option that best fits your study timeline.

There’s no one-size-fits-all answer. How much time you need depends on your schedule, your learning and processing style, your current knowledge, and how much time you have before your exam.

Generally, we recommend studying 4–6 hours per day, 5 days per week, for approximately 4–6 weeks.

However, that is a guideline—not a requirement. Some students need more time, while others need less. Your study schedule should work for you and what your performance is telling you that you need.

450 Formula is a video-based NBCOT® learning platform designed to help you learn, retain, and apply the content you need for exam day.

Depending on your enrollment, your learning experience includes:

• Video lessons covering major, high-yield NBCOT® topics
• A structured study plan
• Active recall and spaced repetition built into your learning
• Flashcards
• Knowledge checks and practice questions
• Video question breakdowns with Kim and Miles
• Progress tracking to help you identify where you need more work

Everything is designed around one goal: helping you turn what you’re studying into knowledge you can actually use on the exam.

Both!

450 Formula includes dedicated learning paths for OTR® and OTA exam candidates. Your learning experience is tailored to the exam you’re preparing to take so you can focus on the content and application most relevant to your exam.

450 Formula is designed for OTR® and OTA students preparing for the NBCOT® exam, whether you’re studying for your first attempt or preparing to test again.

It’s especially helpful if you need support understanding the content, remembering what you’ve learned, and applying that knowledge to exam questions.

You don’t need to know everything. You need to know the right information—and know what to do with it on exam day.

450 Formula is designed to help you learn, understand, retain, and apply the major concepts you need for the NBCOT® exam. However, no study resource can guarantee a passing score or predict every question you’ll see on exam day.

We also recommend incorporating full-length practice exams into your preparation so you can practice timing, endurance, and applying your knowledge under exam conditions.

Your study plan should ultimately be guided by your performance. If your scores show you have a weakness, address it. If they show you've mastered an area, keep moving.

The goal isn't to know everything. The goal is to be ready for 450.

We encourage you to try the free trial before purchasing to make sure 450 Formula is a good fit for your learning style.

If you purchase 450 Formula and find that it’s not what you expected, we’re happy to issue a refund as long as you have accessed less than 5% of the course.

Once you have accessed or completed 5% or more of the course, your purchase is no longer eligible for a refund due to the digital nature of the program and access to our proprietary course content.

We recommend following the 450 Formula study plan whenever possible. The course is intentionally structured to incorporate spaced repetition and active recall to help you retain what you’re learning and revisit important concepts at strategic points throughout your studying.

However, you are not required to follow the course in order. You can move through 450 Formula based on your individual needs and prioritize the topics where you have the greatest weaknesses.

Follow the plan when you can. Prioritize your weaknesses when you need to.

Yes, in certain situations.

If you complete 450 Formula and do not pass your NBCOT® exam, we’ll stick with you. You can request an extension by submitting your extension request along with documentation of your exam results.

If you have not taken your exam yet and simply need a little more time, we offer a complimentary 1–2 week extension.

Need longer than that? Additional access can be purchased to give you more time to continue studying with 450 Formula.

Yes—but 450 Formula is not a practice question or exam simulation platform.

450 Formula is a video-based learning platform designed to help you learn and understand NBCOT® exam content.

Practice questions are included throughout the courses to help you see how the content you’re learning may be presented in a question and practice applying what you know.

You’ll also see videos of Kim and Miles breaking down questions, so you can learn how to think through the question, apply the content, and understand the reasoning behind the answer.

If your primary goal is to take large sets of practice questions or simulate the full NBCOT® exam experience, you’ll want to use a dedicated exam simulation resource (such as TMPOT or NBCOT study pack) alongside 450 Formula.

No course can predict every topic or question that will appear on your exam. Instead, 450 Formula focuses on the major, high-yield topics you need to know and helps you understand them in a way that you can actually apply on exam day.

Our goal isn’t to teach you everything that could possibly be tested. It’s to help you build a strong foundation in the concepts that matter most.
