About this app

The first stage of the Level 1 Civil Engineering Construction Management Engineer examination consists of answering 70 questions out of 101 questions in sections A and B. Since only 10 questions are selected from 34 in the specialized civil engineering section, the key to passing or failing lies in where you score points: roads/paving, rivers, tunnels, railways, and water/sewerage systems. A passing score requires a total of 42 or more correct answers, plus at least 9 out of 15 questions in the construction management methods (applied skills) section of section B. This app contains 399 questions from four examinations held from 2023 to 2026, and includes explanations for the correct answer and why the other options are incorrect for every question.

■ Strategies for this Exam
- Strategies for Multiple-Choice Questions: The general civil engineering section (12 out of 15 questions), specialized civil engineering section (10 out of 34 questions), and regulations section (8 out of 12 questions) are categorized into "primary," "backup," and "later" based on the correct answer rate for each type of work and field. The number of questions for the specialized civil engineering section is also displayed as it is typically the number of questions asked each year.
- The Home page's passing criteria card has two meters: "Overall 42/70" and "Applied Ability 9/15". This shows how many questions are needed in each section, and allows you to solve 10 questions in each section focusing solely on applied ability.
- The mock exam follows the format used from fiscal year 2024 onwards, with Question A at 150 minutes (including 5 questions on basic civil engineering) and Question B at 120 minutes. You cannot select more than the specified number of categories, and the results are displayed using two criteria and the number of correct answers for each category.
- Schedule Lab: Calculate the critical path, connection point time, and float of a network schedule, and the output of a bar chart, changing the numbers as many times as you like. The solution method is shown step by step with diagrams.
- For the "Number of appropriate items" in the applied ability section, the correctness and reason are displayed for each of the four descriptions ① to ④. Identify which part of the description you misread
- For the 2023 (Reiwa 5) exam, use the format before the addition of Civil Engineering Fundamentals (65 questions to answer, 37 for passing), practicing according to the standards of that time.
