This paper explores Malaysian students' problems within their science and engineering tertiary courses in Japanese through their diary entries and semi-structured interviews. The study analyses how students implement management strategies to overcome their problems. Although many studies are available regarding students' academic activities in a foreign language, few of those have reported upon foreign students' academic experiences in Japanese science and engineering courses within their in-country program. The students predominantly had difficulties in writing experiment reports, understanding scientific concepts, and reading Chinese characters (kanji). Management strategies that they significantly employed to overcome their problems were peer cooperation and the use of internet resources. The paper discusses potential support that the program and the language course can provide for these students. (Contains 2 figures and 1 table.)
