ESL (English as a Second Language) Lectures, targeted at graduate students at the Department of Mathematics and RIMS, focus on developing the students’ ability to convey mathematical ideas in English. Through the lectures, students gain experience and knowledge about the ways and rules of communication in English as well as fundamental writing skills required for producing scientific papers.

ESL Lectures are open to all graduate students at the Department of Mathematics and RIMS. However, when the number of applicants exceeds the limit, master's students, especially those who intend to pursue doctoral studies, will be prioritized. Although one credit valid for the Top Global Course is awarded upon successful completion, it is not required to enrol in the Top Global Course in order to attend ESL Lectures.
