For the Industrial Safety Engineer written exam, passing depends more on how you review than on how many questions you solve.

The Industrial Safety Engineer app is not just an app that increases the number of practice questions. It focuses on pinpointing your current weaknesses and bringing back questions you have already solved just before you forget them. Because the cognitive science-based FSRS algorithm analyzes the forgetting curve for each question to automatically determine the optimal review time, the amount of information retained differs significantly even with the same amount of time invested. Even if you have limited study time due to field work, 30 minutes before work and 1 hour after work is sufficient.

[Key Features]

Over 1,000 questions covering the entire range of 6 subjects

Covering Industrial Accident Prevention and Safety & Health Education, Ergonomics and Risk Assessment Management, Machinery, Equipment & Facilities Safety Management, Electrical Facilities Safety Management, Chemical Facilities Safety Management, and Construction Safety Management. It was developed in-house to reflect the 2024-2026 NCS examination standards.

Frequency of Questions by Session

We analyzed 1,658 questions from 14 sessions spanning 2018 to 2022 to identify key topics by subject. It helps you use your limited time effectively in areas that appear in almost every session, such as defect count and reliability, industrial safety regulations, and presses and shears.

Detailed Explanations

Explanations are provided for every question. You can move on without simply checking the answer, understanding the concepts behind why that answer is correct. We have also summarized the legal grounds of frequently tested industrial safety and health laws. You can preview up to 5 sessions of in-depth detailed explanations for free.

Various Solution Modes

You can select and solve problems by subject or chapter, and progress and proficiency levels are displayed for each chapter. You can start with unsolved problems or focus on weak chapters. You can also practice like a real exam using Shuffle Mode, where questions appear randomly from all subjects.

Built-in Scientific Calculator

A scientific calculator is available for immediate use without leaving the screen while solving problems. It supports trigonometric functions (sin, cos, tan), logarithms (log, ln), square roots, powers, and pi, allowing you to solve problems requiring calculations on the spot, such as quantitative assessments of reliability and risk.

FSRS Smart Review

It extends the review interval for questions you answer correctly and quickly revisits questions you frequently get wrong. You don't need to create a review schedule yourself; the app takes care of the questions you need to review today.

[Content Guide]

The Industrial Safety Engineer app does not include past exam questions. This is because the written exam for the Industrial Safety Engineer certification is conducted via computer-based testing (CBT), so actual exam questions are not publicly available. Furthermore, since the copyright for past exam questions belongs to the administering body, copying and pasting them verbatim is not permitted. Instead, we have analyzed the National Competency Standards (NCS) criteria and created study questions tailored to the format and difficulty level of the actual exam. The questions are composed of core question types with a high probability of appearing on the exam, and we do not restore or reproduce past exam questions.

This app is intended for studying for the Industrial Safety Engineer written exam; it does not provide separate content for the practical exam.
