About this app

Questions regarding legal provisions are often answered incorrectly not because the provisions themselves are unknown, but because the answer choices miss subtle changes to the provisions.

Lee Ji-eun's Law Guide is an app that breaks down past PSAT Situational Judgment legal provisions questions into answer choices, training you to identify "where the provisions have changed."

Calculation, rule, and probability problems are presented as step-by-step quizzes, designed so you can solve them simply by following the steps, without having to organize the conditions in your head.

■ How to Train

· Verification Type: Look at a single legal provision and answer choice to determine O or X. If it is X, directly identify the incorrect statement within the answer choice.

· Case Type/Situation Type: Solve an entire problem as if in a real exam. Select the answer by eliminating answer choices by clicking on the incorrect statement.

· When you grade, the app displays the traps found in that answer choice (changing the subject, changing the object, changing the duration or numerical value, changing clues or exceptions, etc.) along with the explanation.

■ Today's 10 Cards

Ten cards worth of material are randomly selected from all past questions every day. It takes just over 5 minutes to complete, making it ideal for daily practice.

■ Step-by-Step Quiz

· For every 13 units, use 'One Thinking Sheet' to first review the thought sequence for that unit.

· Solve 586 past exam questions step-by-step. As you select an answer, the table and notes are filled in immediately.

· Once you finish, the original question is displayed along with a review of which stage of thought you wrote for that problem.

· Quiz: Today's Question: Solving one question a day on the Home page uploads your record to the Fizzle League.

■ Identifying Your Weaknesses in Numbers

· Trap Report: Shows which traps you frequently fall into and how well you identify them when you encounter them, categorized by type.

· Questions to Review: Collect cards you got wrong or cards where you answered correctly but failed to identify the trap, and solve them again.

· Learning Statistics: View your accuracy rate, solution speed, and trends by question type.

■ Scope of Coverage

Past legal provisions from the PSAT Situational Judgment section of the Level 5 Public Service Exam, Level 7 Public Service Exam, and Private Sector Career PSAT. It follows Instructor Lee Ji-eun's type classification (Verification, Case, Situation).

Explanations are written in the order of supporting legal provisions → application → conclusion → error in answer choices.

The Step Quiz consists of 586 questions covering calculation, rules, and probability from past Situation Judgment exams since 2008.
