Single-select and multiple-select items are supported where applicable. Immediately after answering, check the correct-answer explanation and the reasoning for every choice so you understand both why the answer is correct and why the alternatives do not fit. Structured study and records β€’ 50-question set learning plus domain, subdomain, and difficulty filters β€’ Immediate grading, correct-answer explanations, and choice-by-choice rationales β€’ Separate saved progress and resume for set, domain, and difficulty study and for mock exams β€’ A study-history calendar with daily question and key-term activity, monthly totals, and study streaks β€’ Review of wrong answers, repeated misses, review notes, and weak-area analysis β€’ Timed mock exams that hide explanations until submission, allow answer changes before submission, and show results by domain β€’ Weekly goal reminders with a configurable notification time β€’ Light, dark, and system themes A smooth learning flow Move quickly among Home, Study, Review, Mock Exam, and Settings. Each mode keeps its own learning state, and moving to the next item after a long explanation automatically returns the new question card to the top. Basic terms and optional audio study Use the basic-term flashcards as the primary memorization tool. When useful, turn on automatic audio playback to repeat key terms while walking, resting, or preparing for sleep without continuously reading the screen. The questions in this app are current as of August 2026, and we plan to review and update every exam’s question bank at least once a year. The questions are independently authored for study and do not reproduce live exam items, dumps, leaked questions, or third-party question banks. This is an independent study app and is not affiliated with, endorsed by, or sponsored by any certification body, exam provider, or trademark owner.
