About this app

The Korean excavator operator written exam, in your pocket.

451 questions built directly around the six main sections of the official
HRD Korea exam standard, every one with an explanation, so a first-time
candidate can simply work through them in order.
No sign-up. No internet connection needed.

■ CBT mock exam, just like the real thing
· 60 questions drawn automatically in the official proportions (60-minute timer)
· Navigate questions from an answer sheet screen like the real exam
· Instant pass/fail against the 60 out of 100 standard
· Leave mid-exam and resume where you left off

■ Wrong-answer notes that sort the wheat from the chaff
· Questions you get wrong are collected automatically
· Answer one correctly three times running and it graduates off the list
· Add your own note to any question
· Filter by unit, sort by how often you missed it

■ Study by unit
· Inspection / Travelling and operation / Structure and function / Safety management
Construction machinery and road traffic law / Machine systems
· Broken into 25 short sub-topics
· Pick an answer and see the correct one with its explanation straight away

■ Statistics that show your weak spots
· Automatic weak-unit analysis from your accuracy per unit
· Mock exam score trend graph
· Two-week study volume and study streak
· "Weak spot drill" collects only the questions you get wrong most

■ And more
· Random mock exam - choose the range and the number of questions
· Bookmarks - gather the questions that keep tripping you up
· Search - keyword search across question text, options and explanations
· Dark mode and adjustable text size
· Shuffle questions and options so you cannot memorise answer positions

■ Multilingual support for foreign learners
· 한국어 / English / Tiếng Việt / ไทย / Bahasa Indonesia / 中文
· All 451 questions fully translated into English
· The real exam is set in Korean, so a side-by-side mode shows the Korean
original underneath the translation
