Version 1.2.0 doubles the question bank and adds tools that show you how well you really know the material. NEW - More than 2,300 practice questions, up from about 1,150, with new coverage of training and communication, emergency response, first aid, fire prevention, security, hazard communication, PPE and respirators, safety math, hearing, and recordkeeping. - 132 more flashcards, for 648 in total. - "How sure are you?" Rate each practice answer as Sure, Not sure, or Guessing. Questions you got wrong while sure are flagged as misconceptions, and right answers you guessed are treated as not yet learned. - Pacing & Habits report after every mock exam: time per question, rushed misses, questions that took long and were still wrong, right answers that were slow, and how often you changed an answer. - Wrong Answers Book now has a "Sure but wrong" filter. - Question Cards put your misconceptions first. - Readiness scores give partial credit to right answers you were unsure about, and Progress explains what is holding each exam area down. - With an exam date set (PRO), flashcard reviews are spaced so cards come back before test day. IMPROVED - Clearer wording on every screen, with consistent names for mock exams, practice, and review. - Percentages now read 88%, and plurals such as "1 question" and "3 questions" are correct throughout. - Clearer error and limit messages, and friendlier study reminders.
