About 전기기사 필기 - 전기자기학 전력공학 CBT 대비
For the Electrical Engineer written exam, the outcome is determined not by how many problems you solve, but by how long you retain what you have solved.
Learn five subjects—Electromagnetics, Power Engineering, Electrical Machinery, Circuit Theory and Control Engineering, and Technical Standards for Electrical Installations—all in one app. You can organize your daily tasks by linking problem-solving, explanations, reviews, and mock exams for each subject.
[Key Features]
Full-range learning by subject
Learn the five subjects by dividing them into subjects and units. You can view unit progress and answer rates to identify areas you haven't yet solved or areas where you are weak.
Self-produced questions and explanations
We have included study questions tailored to the exam scope and the multiple-choice format (four options). You can check the explanations to see not only the correct answer but also why that answer is correct and why other options are incorrect, allowing you to apply that knowledge to subsequent problems.
Selective problem-solving by subject and unit
You can directly select the subjects and units you wish to study. You can adjust your study order by continuing to review problems you haven't solved yet or by re-solving only the necessary ranges. Initial Diagnosis
At the start, you can check your current status with questions from five subjects. This can be used to determine which subject to begin with.
Practical Mock Test
Solve 100 questions within 150 minutes, simulating the structure of the written exam. Each subject consists of 20 questions, and results are checked based on an overall average of 60 points or higher and a minimum score of 40 points per subject. After submission, you can review your scores by subject and the questions you answered incorrectly.
CBT Practice and Scientific Calculator
Practice the flow of solving problems on the screen, aligning with the computer-based exam format. For questions requiring calculations, you can open the in-app scientific calculator to continue the calculation.
Continue Solving
Your progress is saved even if you stop mid-study. When you reopen the app, you can resume your learning from where you left off.
FSRS Smart Review (Premium)
Calculates the next review time based on your question-by-question solution history. You can extend the time interval for questions you remember well and revisit frequently confusing questions at an earlier time. Weakness Heatmap and Learning Completion (Premium)
View correct answer rates by subject and unit at a glance and identify your weak areas. Based on your study records, you can review remaining areas and select your next study scope.
Question Frequency Analysis (Premium)
Check the proportion of questions by unit to determine your study order. Organize the areas you will review first based on your remaining time and your weaknesses.
Review Box and Error Notes
Incorrect answers are automatically collected in the review box, and you can manually add necessary questions. Find questions to review using sorting and filters, and leave notes for each question to record why you were confused.
My Notes
Collect and review the notes you made while solving problems. Organize information needed for your next review, such as formulas, conditions, and reasons for mistakes, along with the questions.
Study Report and Statistics
Check reports reviewing your daily study, daily problem-solving counts, correct answer rate trends, and consecutive study days. You can adjust the scope of your next study by reviewing your accumulated records.
Weakness Heatmap and Learning Completion (Premium)
