On the PSAT, you often get even the questions you know wrong due to a lack of time. Past questions are already publicly available. What is truly lacking is not the score—but the ability to decide within the time limit when to tackle a question and when to skip it.

Daily PSAT is not a question bank; it is an app designed to measure and train that decision-making ability.

■ Measurement — See your actions, not just the correct answers

· Record time allocation, decisions to discard, and sunk costs (holding on until the end) for each question

· Diagnose behavioral tendencies: Sunk Cost Type / Hasty Discarding Type / Time Over-investment Type / Balanced Type

· Mark the trajectory of how those tendencies change over several days

· Triage coaching immediately after solving: "Should have discarded this question / Should have kept this one"

■ Senses — Building the foundation of data interpretation and verbal logic step by step

· 8 types of numerical sense: Estimation, Fraction Comparison, Growth Rate, Proportion, Multiple, Weighted Average, Unit Conversion, Pitfalls

· 7 types of logical sense: Proposition, Contrapositive, Sufficient/Necessary, Syllogism, Negation of Quantifier, De Morgan's Rule, True/False Inference, Logic Puzzles

· Internalize through daily repetition in levels 1 through 3

· Repetitive practice with new problems generated every time based on rules — Offline available

■ Solution — Just like an exam paper

· 1,050 questions (independent verification), Verbal Reasoning, Data Interpretation, Situational Judgment

· Practical mock exams (one section, one time limit) + analysis of where time wasted

· Error Notes: All answer choices, highlighting, organizing my errors, and repetitive review at intervals

· Memo and drawing tools during solution (for data calculations)

■ Past Exam Materials

· Actual past exam questions are publicly available. Direct links to yearly formulas and public sources (Cyber National Examination Center, Public Data Portal, etc.) are provided.

This app is not a substitute for past exam questions. Please solve actual past questions separately; use this app to train "how to solve them (time allocation, discarding questions, and intuition)." These are aspects that cannot be cultivated through past questions alone.

Target Exams: PSAT for Grade 5 Public Service Exams (Administrative Examination), Grade 7 Public Service Exams, and Private Sector Career Professionals, etc., and Public Service Aptitude Test. All sections of Verbal Reasoning, Data Interpretation, and Situational Judgment.
