What you will learn
How it works
Start free, no account needed
The first 12 lessons are completely free. Open any lesson and begin — no sign-up, no email required. Progress is saved once you begin learning.
Every lesson combines explanation, audio, and practice
Lessons give you clear explanation of grammar in English, reading texts in Russian, and interactive exercises — all completable in the browser. Audio is recorded by educated native speakers, not synthesized voice.
Structured to build on itself
Each lesson is a logical continuation of the previous one, using only vocabulary and grammar you already know. You can return to any lesson at any time.
Continue with Corrus or the Resonance textbook
After the free lessons, choose your path: subscribe to Corrus for the full online course, or continue independently with the Resonance textbook — or both.
