You got the answer right, but can't explain why?

Shin Sung-woo's Zeroing is an app that trains you by breaking down past Civil Service and PSAT questions into individual answer choices. The exam ultimately comes down to judging the correctness of five answer choices. However, most people just pick the correct answer and skim over the rest. Those ambiguously skipped choices will trip you up in the exam room.

Just as you zero in a gun, aim precisely at each and every answer choice.

■ True/False Training by Answer Choice

We divide a past exam question into True/False cards for each answer choice. Since this training involves judging "why this answer choice is right / why it is wrong" one by one based on the original text, it builds genuine skills rather than just guessing.

■ Reading Comprehension Training — Read Less, Judge Accurately

High scores in Verbal Reasoning depend on reading less than others while judging answer choices quickly and accurately. We train on a single past exam passage in three stages.

· Skipping the Framework — Grasp the structure first by identifying the connections of information. Illegible details that can be looked up later, such as years and figures, and skim only the framework necessary for judgment.

· Finding Evidence & Judgment — Look at the answer choices, go back to the passage, tap the supporting sentence directly, and select Correct / Incorrect / Undecidable.

· Comparison — Place the evidence you selected side by side with the actual evidence to identify where they differ.

Reading speed and evidence accuracy are recorded at each stage, separating "errors caused by failing to find evidence" from "errors caused by finding evidence but making a wrong judgment."

■ Practical Set Practice

Solve all questions from that year consecutively, timing yourself as if in an actual exam, using the original question and the five answer choices in their original order. Skip any questions you get stuck on and return to them at the end. There are no aids.

**Solve all questions from that year consecutively, timing yourself just like in a real exam.** ■ Included Past Exam Questions
