Best wedge to reach the first 100 paying medical-residency candidates in Brazil?

MED.Z is a premium study-planning platform for Brazilian medical residency candidates. It organizes weekly study, past exams, reviews and performance by specialty/topic, with an AI tutor that turns this history into priorities.

I’m comparing three early acquisition wedges: partnerships with medical-student communities, creator-led cohorts, and a focused referral program around target exams such as ENARE and USP-SP.

For a high-intent, seasonal B2C education product, which wedge would you test first — and what leading indicator would make you double down within 30 days?
