For the Public Service Aptitude Test (Basic), it is more important to review necessary content in a timely manner than to solve a large number of problems.
Prepare for the three subjects of Verbal Reasoning, Data Interpretation, and Situational Judgment in one app. It includes 375 past Grade 7 exam questions from 2021 to 2025, along with self-produced questions for each subject, accompanied by detailed explanations. FSRS calculates the next review time based on your memory status for each question.
[Key Features]
Full-range learning by subject
Learn the three areas of Verbal Reasoning, Data Interpretation, and Situational Judgment by dividing them into subjects and units. Progress and correct answer rates are displayed for each unit, allowing you to identify and focus on areas you haven't touched yet or your weak points.
375 Past Grade 7 Exam Questions
We have included five rounds of the 1st Grade 7 Public Service Recruitment PSAT from 2021 to 2025, organized by subject: Verbal Reasoning, Data Interpretation, and Situational Judgment. You can select a round and solve the questions in the order of the actual exam papers, and explanations for each answer choice are provided for all past questions. The tables and graphs feature the exact data from the original exam papers. You can select to solve only past exam questions, only self-created questions, or both in the settings.
Self-Created Questions and Detailed Explanations
We have included study questions across all chapters tailored to the exam scope and the 5-option multiple-choice format. To ensure you do not just check the answer and move on, we have explained why that answer is correct and why the other options are incorrect.
Mock Exam
Just like the actual exam, the test is divided into two sessions. Session 1 consists of 50 questions on Verbal Reasoning and Situational Judgment to be completed within 120 minutes, while Session 2 consists of 25 questions on Data Interpretation to be completed within 60 minutes. Since time runs separately for each session, you cannot concentrate all your time on a single section. You can check results by subject based on the passing threshold of scoring at least 40% of the maximum score for each subject. If you fail to meet the standard in even one subject, the score will not be offset by the scores from other subjects. The passing score for the total score varies by session and is not announced in advance. After completing the test, you can review your scores for each subject and the questions you answered incorrectly all at once.
The tables and graphs are included exactly as they appear on the original exam papers. Initial Diagnosis
