FAQs

Is this aligned with USMLE Step 1 blueprints?+

Yes. All content is mapped to NBME Step 1 content specifications — organ systems, disciplines, and physician tasks as defined in the most recent blueprint.

How does Synapses help with Step 1?+

Synapses trains concept-linking under time pressure. You group related terms, beat the clock, and compete on leaderboards — which builds the associative memory that Step 1 high-yield questions test.

How long is the free trial?+

Start free and explore questions, flashcards, and lessons before upgrading. No credit card required.

When should I start using Oncourse for Step 1?+

Most students start 4–6 months before their exam date. The spaced repetition system works best with time — the earlier you begin, the more recall loops you complete before test day.

Yes. Oncourse is available on iOS and Android. Study on your phone, tablet, or desktop — progress syncs automatically across all devices.
