See which quartile you land in
Every response is placed in a quartile from Q1 to Q4, with scores across the competencies Casper looks for, plus what you did well and what to fix.

Watch the answer guide
Every scenario comes with a video answer guide. It walks through the framework, then shows a typed and a spoken 4th-quartile answer to compare with your own.
Every question, on the clock
Scenarios unfold over several questions, each with its own timer, so you practise thinking on your feet the way test day demands.

Get eyes on it from real people
Share a link with a friend, mentor or fellow applicant. They place your response in a quartile, rate it across key criteria and leave written comments.

You heard both sides before judging, which reads as mature. End with one concrete next step so the plan feels finished.
Our AI catches patterns.
Your peers catch the blind spots.

Peer Feedback from Jessica C.
Submitted 2 hours ago
A colleague frequently interrupts others during team meetings...
“Your response showed great empathy for all parties involved. I liked how you considered the colleague's perspective while still addressing the issue directly. One suggestion: you could strengthen your answer by including a specific example of how to start that private conversation.”
Less than one tutoring session.
Pick the timeline that matches how far out your Casper is.
Common questions.
Our simulations mirror the real format: timed sections, typed and video responses, situational judgment scenarios. The UI is designed to match the actual test experience as closely as possible.
We recommend completing at least 3 full-length tests before your real Casper. Each test gives you different scenarios and builds your pattern recognition for structuring responses under time pressure.
200+ programs across medicine, dentistry, pharmacy, nursing, PA, and more in the US, Canada, Australia, UK, and beyond. If your program requires Casper, we cover it.
Sandbox Intelligence analyzes your response across 6 competency dimensions — empathy, communication, ethical reasoning, critical thinking, professionalism, and collaboration — and provides specific, actionable feedback within seconds of submission.
Yes. The custom test builder on Core and Master tiers lets you configure exactly what you want to practice — scenario types, response format, and timing.
Absolutely. You have limited time per scenario. Slow typing means less content, weaker structure, and lower scores. We offer a free Type Racer tool to help you build speed before test day.
Other platforms offer generic coaching or static workbooks. Sandbox gives you the actual test format, AI feedback in seconds, and custom drilling. No Zoom calls. No scheduling. Just reps.
