The Problem

Why most fail at speaking

At some testing centers, more than half of candidates fail — despite knowing the theory and vocabulary cold.

The practical exam — where most fail

Theory is learnable. But speaking practice only happens in courses — if at all. Some testing centers have a failure rate above 50%.

No practice partner at midnight

Online courses have fixed schedules. Your instructor has limited slots. Want to practice at 10 PM on your couch? Not an option.

Feedback only at the exam

You practice for weeks and only find out on exam day whether your readback is correct. It doesn't have to be this way.
