Learning Spanish stops feeling random when you can see the map. WorldsAcross™ gives you a real curriculum — levels, units, and clear goals — plus live classes with tutors who teach it. You always know where you are, what this class works on, and what comes next. A roadmap you can see My Journey shows your level, your unit, and the specific thing you're learning to do right now — telling a longer story in the past, adjusting how formal you sound. Every activity connects to that goal, so no class is a one-off. Know what you'll learn before class starts Open a lesson and the plan comes first: what you'll practice, which structures you'll use, and why they matter in real conversation. You arrive prepared instead of guessing. Live classes, one-on-one or in a group Book 25- or 50-minute private classes, or join live group sessions and conversation practice. Levels and open spots are shown up front, and when a session fills up you can join the waitlist. Tutors you choose, not tutors you're assigned Browse vetted tutors from across the Spanish-speaking world. Watch their intro video, read their background, see how many lessons they've taught. Same lesson, different tutors — you decide who teaches it. Two ways to book, switch anytime Flexible: all your tutors' schedules in one calendar, swap anyone in or out. Recurring: the same tutor at the same time every week, set once. Your week changes, your booking can too. A coach who knows your level You're matched with a coach you can message anytime — about a structure that won't click, what to work on next, or how a class went. Everything in one place Upcoming and past classes in one calendar. Your progress in hours and classes completed. Practice resources for reading, writing and conversation between sessions. Starting from zero or fine-tuning B1, WorldsAcross meets you where you are and builds from there.
