Peer Feedback from Priya S.

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.

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 charge $125/week or $2,697+ for generic coaching. Sandbox gives you the actual test format, AI feedback in seconds, and custom drilling — starting at $29.99. No Zoom calls. No workbooks. Just reps.
