About this app

Non-fiction is not a subject where you simply wait for a familiar passage to appear. It is a matter of the ability to accurately read unfamiliar passages within a time limit.

Bisuda does not stop at reading past CSAT Korean Reading (Non-fiction) passages after just once. By having you read the same passage three times—each time in a different way—it transforms the "habit of reading by intuition" into "training to read by method."

■ 3-Round Spiral Learning

Round 1 — Reading in Sentences

You break down the passage into individual sentences to check and move on. Instead of skimming through with your eyes, you identify what each sentence conveys before moving on to the next.

Round 2 — Reading the Entire Passage and Deepening

This time, you read the passage you previously read in segments in its entirety. You check how sentences connect and identify the overall structure of the text.

Round 3 — Practice

You face the passage and questions just as if you were taking the actual exam. You solve the problems while building upon the foundation of the previous two rounds.

Since the same passage returns three times, you move on to the next passage only after fully digesting the previous one.

■ Ask a Korean Language Expert

If you simply check the correct answer number and move on when you get stuck on a question, you will likely get stuck again on the same type of question later. Bisuda's "Korean Language Expert" explains which sentence in the passage served as the basis for selecting that option, and why the other options are incorrect, by attaching them to the text.

It is less about reading the explanation and more about observing the problem-solving process.

■ Revisit Incorrect Questions

Remember the questions you got wrong and ask them again using the review cue. You don't need to create a separate error notebook and open it again; the app automatically retrieves those questions.

■ All Past Exam Passages from 1994 to 2026

We have compiled and included past CSAT Korean Reading (Non-fiction) passages organized by year. You don't have to worry about which passage to tackle first; simply build up three readings in order.
