DY STUDY is a mathematics education program led by instructors Park Dong-woo and Jung Yeon-woo. It supports students from the summer of middle school year 3 through the summer of high school year 3, combining exam-focused lessons with detailed learning management. Both teachers prepare and oversee classes, teach the full course directly, and take responsibility for each student’s progress. Park has taught mathematics in Daechi-dong since 2004, and Jung since 2012.

The program offers grade-specific courses, including middle school students’ advanced study and high school courses focused on second-semester school exams. Lessons cover topics such as Common Mathematics, Algebra, Probability and Statistics, Geometry, and Calculus, with school-specific mock exams used for preparation. Admission tests are required for the listed classes, and prospective students can contact the academy for testing and consultation.

Shared learning resources include carefully prepared course materials, cumulative assessments covering concepts, essential problem types, and challenging questions, plus individualized error-review printouts.
