What Practice Test Geeks adds beyond an AI chat for CIW
An AI chatbot can quiz you, but it can't reproduce the exam conditions or keep your record. Here you get:
- A timed, full-length CIW mock exam — 55 questions in 90 minutes with a 70% pass mark, modeled on the official exam's question count and time limit, followed by a score report broken down by exam domain.
- A fixed CIW question bank: the same test every attempt, so your score is comparable from one try to the next instead of changing with every regenerated quiz.
- Progress saved on your device: completed tests, scores and missed questions stay in My Progress, so you can retake only what you got wrong.
- A printable CIW cheat sheet you can print or save as a PDF.
- CIW flashcards built from the same question bank.
- Free CIW practice tests with the correct answer shown after each question.
