Not another knock-off mock test

Questions, scoring, volume — everything is benchmarked against the real exam.

Items

Real structure, dummy items included

The real test hides unscored dummy items. We rebuilt that structure — adaptive routing, distractor design and all.

  • Unscored dummy items, reproduced structurally
  • Adaptive (MST) routing driven by Module 1
  • Distractor types and ratios match the real exam
Scoring

Scores you can act on

The real TOEFL pairs human raters with e-rater and SpeechRater. Our engine implements those same published axes — so the score itself tells you what to fix.

  • Four error rates: grammar, usage, mechanics, style
  • Lexical level & diversity, development, coherence
  • Pronunciation, fluency, prosody and content — in precision scoring
Volume

70 full-length mock tests

Practice one a day and it still lasts over two months. You will not run out before test day.

  • 70 full-length mocks
  • 6,000+ original questions
  • Every question passed a 37-step review
