Test takers engage in multi-turn conversations with animated characters, simulating real-life scenarios such as following up with a professor or asking a friend to review a paper. This innovative approach measures multiple language skills simultaneously, reflecting how language is used in real life.

6. Comprehensive Proctoring for Test Integrity

Each test session is recorded via computer, microphone, keyboard, and mouse, and reviewed by trained professionals in multiple rounds. AI assists human proctors in examining over 75 different behaviours to detect any suspicious activity, ensuring the test's integrity.
