The purpose of this study is to show that the preference of mathematics learning strategies for high school students can be different according to students’ cognitive ability style such as logic, working memory, long-term memory, implicit memory. For this purpose, 230 students were examined who had excellent grade on College Scholastic Ability Test Math Section. In order to measure their cognitive ability style, Cognitive ability style test(Choi, 2017) was used, and the Learning Strategy Scale was developed to research the preferences about math learning strategies. Cross analysis process with chi-square test was conducted by means of program R 3.4.3 for Windows. The result of this study showed the relationship between cognitive ability styles of high-achievers on CSAT and their learning strategies. The result showed that there was a significant relationship about two strategies with logic, one with working memory, three with long-term memory, and two with implicit memory. The result implies that in the case of studying math for the exam, general learning strategies may be ineffective, rather personalized strategies according to cognitive ability style would be more effective.
