A client with right hemiparesis after a stroke is relearning to put on a button-down shirt. Which step should the OT teach first?
Put the affected (right) arm in the sleeve first
Why it's right: dressing the affected limb first leaves slack for the stronger arm.
Put the unaffected (left) arm in first
Why it's wrong: the shirt is then too tight to reach around the weaker arm.
Textbook page cited for each explanation
Readiness estimate (example)
300-600 scale
The shaded band is the uncertainty. It narrows as you answer more questions.
Why another prep tool
Built around the most common complaints about NBCOT prep
The same six complaints come up again and again in student reviews and forums. Each one shaped a feature.
“Practice scores don't predict the real result”
Our readiness estimate shows an uncertainty band and tells you how much data it rests on, instead of a single confident number.
“Official practice tests are single-use”
Full-length simulations are unlimited. Take one, review it, take another.
“Rationales only explain the right answer”
Every option is explained, with a textbook page you can check.
“Too few scenario-set questions”
Scenario sets let you follow a clinical case across four related questions.
“Prep is expensive”
Start free, then pay once from $39. No subscription, nothing renews.
“Little help for retakers”
Retake mode builds your plan from your NBCOT score report.
Features
Everything you need between now and test day
One-time price, no add-ons. The free tier lets you try each of these first.
Original items in the real exam format
Written from scratch to the NBCOT OTR and COTA content outlines and grounded in OT textbooks. No recalled or copied exam questions.
- Three- and four-option single-best-answer items
- OTR scenario sets: an opening case, then 4 multi-select items (6 options, select 3) with partial credit
- COTA six-option multi-select items
Every option explained, with a page to check
Each option gets a short why-it's-right or why-it's-wrong explanation and a textbook page citation, so you learn from the distractors as well as the key.
Simulations you can take again and again
Unlimited full-length simulations (180 items for OTR, 190 for COTA, 4 hours), a 40-item diagnostic, and tutor or timed practice sets whenever you want them.
A readiness estimate, labelled as one
We place you on the 300-600 scale with an uncertainty band that narrows as you answer more. It is an estimate from your practice data, not a prediction of your result.
Analytics that show how you miss
Accuracy by domain and by outline task, confidence calibration, second-guessing analysis (what happens when you change an answer) and pacing against the clock.
An AI tutor that shows its sources
Ask about any question you have answered or any topic. The tutor answers from textbook passages and cites the pages. Choose explain, Socratic or quiz-me style.
Flashcards that build themselves
Missed a question? A spaced-repetition card is created from it automatically, so your weak spots come back at the right time.
A plan that works back from your exam date
Set your test date and the study plan adapts to your results. Retaking? Retake mode starts from your NBCOT score report.
How we keep the items honest
- Released items pass independent AI answer and source checks before entering the practice bank.
- Any student can report any item in one click, and reports are reviewed.
- The bank includes hundreds of original items. New items are screened before release.
The exam
Built for the OTR exam as it has run since January 2024
Since 2 January 2024 the NBCOT OTR exam has 180 items in 4 hours. The clinical simulation test (CST) items were retired and replaced with scenario sets. Scores are reported on a 300-600 scale, and 450 is the passing standard.
Single-response items
Three- and four-option multiple choice with one best answer. Most of the exam looks like this.
Scenario sets
An opening scene describes a client and setting, followed by four related multi-select items with six options each. You carry the case in your head across all four.
How we practise them
Our OTR scenario sets follow that shape (select 3 of 6) and award partial credit, so you can see which part of your reasoning held up. COTA candidates get six-option multi-select practice too.

Competitor prices and counts are as advertised on their sites when we checked on 3 October 2026 and may have changed. A dash means we did not verify that feature, not that the product lacks it. Larger banks exist: we focus on explanation quality, exam-format items and honest feedback. Product names belong to their owners; we are not affiliated with any of them.

FAQ
Straight answers
How does the free trial work?
Your trial starts when you create your account and lasts 72 hours. Try the full practice bank, simulations, study plan, analytics and flashcards, with up to 8 AI tutor requests per day subject to shared service limits. No card is required and you will not be charged automatically. Choose a one-time pass when the trial ends to keep studying. Your history and account remain available.
Is OT Prep Lab affiliated with NBCOT?
No. OT Prep Lab is an independent study tool. It is not affiliated with, endorsed by or sponsored by NBCOT®, and we have no access to live exam items.
Are these real exam questions?
No. Every item is original, written to the NBCOT OTR and COTA content outlines and grounded in OT textbooks. We do not use recalled or copied exam content.
How many questions are there?
Hundreds of original items today. New items become available after quality review. We put our effort into explaining every option and matching the current exam format.
How accurate is the readiness estimate?
It is an estimate, not a prediction. It places you on the 300-600 scale with an uncertainty band that is wide when you have answered few questions and narrows as you do more. Treat it as one signal among several.
Can I trust the AI tutor?
The tutor answers from textbook passages and shows the PDF page it used, so you can check it. Like any AI it can be wrong. If something looks off, check the cited page and report it. Daily message and shared service limits apply.
Does it cover both OTR and COTA?
Yes. Choose your exam when you set up your study plan. OTR candidates get scenario sets; COTA candidates get six-option multi-select items and the 190-item simulation.
Is this a subscription?
No. Every pass is a one-time payment for a fixed number of days. Nothing renews automatically.
What is your refund policy?
If you ask within 7 days of buying and have answered fewer than 50 questions on the pass, we refund you in full.
How does the pass promise work?
Complete at least two full-length simulations during your pass. If you then sit the exam and do not pass, email support and we will extend your access for 6 months at no charge. It comes with the Until you pass plan.
I already failed once. Will this help?
Retake mode uses your NBCOT score report to focus your study plan on the areas that need the most work.
