Frequently Asked Questions
Is the ICC E2 vocabulary game free?
Yes. The game is free to play with no sign-up. Signing in adds AI explanations for any term.
How do the ICC E2 vocabulary games work?
There are 4 games built on 20 ICC E2 terms. In Guess the Term, a clue describes one term and you have six tries to spell it, with green, yellow and gray letters showing how close you are. In Term Match, six terms appear as colored tiles; swap neighbors to line up three or more of the same term, and each match shows what the term means. In Term Pairs, twelve face-down cards hide six pairs of terms; flip two at a time to find each pair, and every pair you find shows what the term means. In Term Search, five terms hide in a grid of letters, reading across, down or diagonally; drag across a term to circle it, and each term you find shows what it means.
Where do the ICC E2 terms come from?
OpenExamPrep researched each term from the ICC (Pearson VUE / PRONTO) content outline and primary sources, listed under Sources on this page. The game is independent study material, not an official exam resource.
What score do I need to pass the ICC E2 exam?
The ICC E2 exam requires a scaled score of 75. ICC does not publish a fixed raw-to-scaled conversion, so do not interpret 75 as exactly 60 correct answers or 75% raw. Passing candidates receive a pass result rather than a numerical score.
Is the ICC E2 exam open-book?
Yes. ICC's E2 outline identifies the exam as open book. Verify the approved reference edition and alteration rules for the exact code cycle and delivery method selected in the current Exam Catalog.
