Frequently Asked Questions

What’s the best way to practice clinical reasoning in medical school?

One of the most effective ways to build clinical reasoning is by working through interactive patient case simulations. Sketchy offers real-time, scenario-based learning where medical students make diagnostic decisions and receive personalized feedback—ideal for shelf exams, Step 2, and clinical rotations.

How can I prepare for rotations if I haven’t had much patient exposure yet?

You can develop clinical confidence with virtual case encounters that simulate the patient interview and diagnostic process. Sketchy’s interactive cases let you test your knowledge, interpret labs and imaging, and practice asking questions in a risk-free learning environment.

Are there case simulations that help with OSCE prep for med students?

Yes! Sketchy’s case-based simulations are designed to reinforce the communication and clinical decision-making skills needed for OSCEs. These realistic scenarios help you think on your feet and manage common patient presentations across various specialties.

Can Sketchy help me prep for shelf exams and Step 2 CK?

Definitely. Sketchy’s interactive patient cases include board-style clinical vignettes that reinforce the clinical reasoning needed for shelf exams, Step 2 CK and Step 3 CCS. The cases cover core rotations like internal medicine, surgery, OB-GYN, pediatrics, and more.

Who writes the clinical cases on Sketchy’s platform for med students?

All Sketchy cases are developed by board-certified physicians and medical educators to ensure accuracy and clinical relevance. The content aligns with real-world medicine and exam blueprints, so you can trust that what you’re learning will show up in practice—and on test day.
