Three ways to practice out loud
Choose the practice mode you need today: take a complete Full-Length Oral Exam, work through a developing Main Case from stem review to feedback in a shorter window with a Short Oral Exam, or sharpen your speaking cadence with Question Drills.
When you have 20–30 minutes
Short Oral Exam
Work through a coherent developing Main Case from stem review to feedback in a shorter window, without a Grab Bag section.
When you have a few minutes
Question Drills
Practice one clinical decision or explanation with response-aware follow-up and immediate feedback.
Question Drills
Turn spare minutes into Question Drills.
Build the habit of answering aloud without waiting for a complete case or a scheduled mock. Each question stands on its own rather than entering a Full-Length Oral Exam or Short Oral Exam.
One focused task
Drill a clinical decision, explanation, or mechanism without entering a longer case.
Follow-up that listens
Focused clarification or rationale questions respond to the substance of your answer.
Feedback while it is fresh
Review feedback on the answer you just gave, then move to another question.
One answer changes the next question.
Question Drills give you one clinical decision to explain aloud. The examiner listens to your reasoning and uses focused follow-up when your answer needs clarification or the conditions change.
A few minutes, used well
Practice one complete clinical decision or explanation without entering a longer case.
Reasoning changes the exchange
The next question responds to the substance of your answer instead of following a fixed script.
A clear next improvement
End with focused feedback tied to the response you just gave.
One answer changes the next question
The candidate says elective surgery should be delayed. The examiner immediately changes the decision: what if the operation is urgent and cannot safely be deferred?
One complete Full-Length Oral Exam, from stem to feedback.
The 35-minute Full-Length Oral Exam is the core realistic practice experience: a developing Main Case followed by the exam-style Grab Bag section, with one feedback packet grounded in the complete exam.

Review
Receive session feedback
See scores that track your progress over time, plus strengths, gaps, safety concerns, and clear priorities tied to what you said.
A developing main case
Questions build on your earlier decisions and changing clinical information
Management and knowledge together
Practice prioritization, physiology, rationale, and safety in the same connected examination.
Professional pressure without coaching
The examiner expects a clear plan and does not correct you during live questioning.
ADAPT EXAM SETTINGS TO YOUR GOALS
Practice the questions you hope they do not ask.
Choose an examiner voice, add High Pressure, and focus case selection on the subspecialties you need to strengthen. High Pressure changes the examiner's demeanor, not your questions or feedback, so practice gets harder without changing the standard.
- Choose from nine examiner profiles with distinct voices, personalities, ages, and genders
- Focus case selection on your priority subspecialties
- Choose a regular or High Pressure examiner style
- Keep the same questions and feedback in either style
Practice settings
Your preferred case mix and examiner style become the defaults for new practice.
Feedback after every practice session
Each session ends with response-linked feedback and practice scoring, so you can sharpen the next answer and track meaningful progress over time.
Feedback at every scope
Get focused feedback after a drill and broader pattern-level feedback after longer practice.
Traceable to your responses
Connect each strength, gap, and correction to what you actually said.
Scores and clear priorities
Use practice scores and saved feedback to follow your progress over time, while seeing the strengths, gaps, and answer structure to work on next.
Immediate Question Drill feedback
One response and its focused follow-up become clear strengths, gaps, and a stronger answer structure.
Built for practice you can return to
Candidates have completed thousands of spoken sessions and answered tens of thousands of examiner questions. A growing library of Full-Length and Short Oral Exams, Question Drills, and Grab Bag scenarios gives you room to return, repeat, and strengthen the answers that need more work.

How practice time works
When you start a live practice session, the time for that practice format is set aside from your balance. Finish early and unused time returns to your balance. If you leave and come back, resuming won't take that time again.
Frequently asked questions
Can I try the examiner before choosing a plan?+
Yes. Create a free account and receive 10 minutes of live practice time for Question Drills, with no credit card required. Each drill includes focused follow-up and feedback tied to your answer. Paid practice plans add enough time for Short and Full-Length Oral Exams; plans differ in practice time, access period, and payment structure. Full Listening Library access is included with Comprehensive Practice.
What makes this more than a voice chatbot?+
The examiner follows a coherent case, listens and responds to your reasoning, supports natural clarification and interruption, and carries the experience through response-linked feedback and future practice.
Is On-Call Board Prep an AI anesthesia oral board simulator?+
On-Call Board Prep uses AI to power its responsive voice examiner, allowing questions and follow-ups to respond to what you actually say. The platform is designed specifically for ABA Standardized Oral Exam practice, with clinically reviewed cases and feedback grounded in your responses.
How does this fit alongside faculty or peer mock exams?+
Human mocks remain valuable for high-touch perspective. On-Call Board Prep gives you an available, repeatable way to practice speaking between them, work on difficult areas, and arrive better prepared for that limited time.
How flexible is practice time if I change formats, repeat, or get interrupted?+
Use your balance across all three practice formats and repeat difficult material whenever it helps. Starting applies the format's initial amount. Finish sooner and unused time returns; continue beyond it and additional active practice uses available balance. Resuming does not apply the initial amount again. Sessions are not interrupted and balances never fall below zero.
What is the Oral Board Listening Library, and how can I access it?+
The Oral Board Listening Library contains clinically reviewed simulated examiner-and-Candidate conversations that demonstrate one strong, coherent approach. Full access is included with Comprehensive Practice for its 18-month access period, including new episodes added during that time. Listening does not use practice time and is not personalized feedback on your own performance.
How does the Comprehensive Pass Guarantee work?+
This is purchase protection, not a prediction of your exam result. For eligible Comprehensive Practice purchases made directly from ON CALL LABS LLC on or after July 30, 2026, complete at least 10 hours of active practice time before the exam and provide official documentation that you did not pass the ABA APPLIED Exam's Standardized Oral Examination. We will refund the amount you paid and provide one complimentary Comprehensive access period for your next attempt, including 20 hours of practice time and full access to the Oral Board Listening Library. Claims must be submitted within 90 days of the official result notice, and the guarantee may be used once per person.
Is this affiliated with the ABA?+
No. On-Call Board Prep is independent preparation software built around the SOE structure. It does not provide an ABA score or pass prediction.
Residency programs

Residency programs can purchase shared live practice hours and Listening Library access for their residents, through a single annual invoice. Program administrators can also manage resident access and monitor usage directly in our fully-featured director dashboard.
