This learning app is designed for the first and second stages of the Grade 1 Electrical Construction Management Engineer Certification Examination. It aims to help you pass with 610 practice questions, 38 textbooks, and 20 illustrated guides. ■ Questions aligned with the actual exam structure The first stage exam consists of 89 questions, of which 60 are selected and scored out of 100 points. This app's mock exams faithfully reproduce this distribution of questions. Electrical Engineering, etc.: 10 questions / Electrical Equipment: 14 questions / Related Fields: 7 questions / Construction Management Methods: 19 questions / Regulations: 10 questions Pass/fail criteria are also the same as the actual exam: Overall score of 60% or higher, and at least 3 out of 6 questions correct in Construction Management Methods (Applied Ability). Even if the overall score exceeds the standard, a lack of applied ability will result in a failing grade. The existence of a minimum passing score is clearly indicated on the mock exam results screen. ■ Understanding with Diagrams Includes 20 diagrams, including wiring diagrams, vector diagrams, and process charts. All diagrams are drawn within the app, so the numerical values remain accurate even when zoomed in.
