Famous for having sent numerous students to the Ivy League, One-Stop Prep boasts its 22 years of expertise in overseas school entrance exams. The curriculum is customized for Korean students based on scientific analysis and data that has made many students achieve high scores in such a short period. 

One-Stop Prep introduced a systematic overseas system program for the first time in Korea in 1997 and has sent many students to prestigious universities in the US such as Harvard, Princeton, MIT and Yale without even a year break. Behind this great feat is its innovative R&D Center that gives a thorough analysis on SAT (Scholastic Aptitude Test) as well as an ultimate study method and direction to students in cooperation with renowned SAT-related institutes overseas. 

When SAT was revised in 2016 after 11 years, One-Stop Prep gave a scientific analysis and introduced the real-SAT like mock test which resulted in still sending students to Harvard, Princeton, Yale, Stanford, Chicago and Cornell in 2017 and 2018 in a row. The mock test especially boasts 0.4% error range with the real SAT thanks to its scientific One-Stop Grader System and the strategic OSP Training. 

Making the most of its fame in the field, One-Stop Prep has been running the International SAT Competition for the last 17 years; it is the Korea’s sole international level SAT competition inviting middle and high school students home and abroad.
