VOCA1(보카원) - 수능 영단어

Introducing VOCA1, a vocabulary book selected by past exam questions.

5,000 CSAT English words ranked by frequency and point value, compiled by analyzing all 4,590 questions from 102 rounds of the CSAT, Mock Exams, and Academic Assessments — you memorize words by seeing the evidence of when and how many times they appeared.

There is no going back. You memorize the words that have appeared first.

■ Why VOCA1?

There are many vocabulary books out there. But do you know who selected those words?

VOCA1 links 85,935 records of questions from 102 rounds of the CSAT, Mock Exams, and Academic Assessments from 2020 to 2026 to each individual word. Rather than ranking words based on frequency, it ranks them by assigning weights to words that were actually answered incorrectly in the CSAT, reading sections, and 3-point questions.

■ Word Receipt — You Can See the Reason for Memorizing

Clicking on a word displays the question records for the past 5 years for each CSAT, Mock Exam, and Academic Assessment. From high-scoring (3-point) question markings to actual past exam example sentences (46,529 English–Korean pairs) — you learn using sentences that appeared on the exam, not fabricated examples.

■ Select only the exam session within the current scope

Dig into the grade level → year → session → question number to learn and test only the words that actually appeared on that exam.
