Frequently Asked Questions

Who is this for?

This community is for anyone studying medicine who wants to stop memorizing and start understanding. Whether you're just starting medical school, preparing for step 1, or simply want to think more clinically..., Medical School Companion will show you how to reason through medicine the way real doctors do.

Did Dr. Tisdall create this program?

Yes — every concept, video, case discussion, and word in the textbook comes directly from Dr. Philip Tisdall. He built this system after decades in patient care and over a decade of teaching thousands of students for Step 1 and beyond. You’ll be learning directly from him each week inside the community.

I’m struggling with Step 1. Will this actually help?

Absolutely. Step 1 is a clinical exam built on pathophysiology. Medical School Companion focuses on connecting the basic sciences to patient care, so you finally understand what each question is really testing — and how to reason your way to the answer.

What do I get when I join?

Our membership includes weekly live sessions with Dr. Tisdall, 150+ systems based lectures, interactive case studies, clinical reasoning question sets, and the full Medical School Companion community for discussion and support.

Is this only for U.S. students?

No — the principles of clinical reasoning apply everywhere. We welcome students from any country, at any stage in their medical education, who want to learn a patient-centered, pathophysiology-based approach.

Can I join if I’m already in clinical rotations?

Yes — in fact, you’ll find it even more valuable. You’ll start seeing your patients through the lens of pathophysiology, which deepens understanding and improves presentation and diagnostic skills.

What if I can’t attend the live sessions?

All live sessions are recorded and archived in the community portal. You can watch anytime, review cases, and join follow-up discussions at your own pace.
