You should spend more time on the department web, not simply asking here. Your question about writing requirement showed that you have not even looked at the program description. That makes us feel not that good.
2. Writing requirement: Students in any Specialist program sponsored by the Department of Computer Science (including Combined Specialist programs) must complete one credit requiring substantial written work in English. The courses accepted for this purpose are listed below. Courses not on this list do not satisfy the requirement without departmental approval. Students in the Major program in Computer Science must take one-half credit from the same list. Departments offering these courses have agreed to accept our students, but will not give you special preference in admission. You must satisfy the prerequisite and other requirements listed in this Calendar. Make sure to check that the course you want to take is offered in the year you want it, and to follow the enrolment requirements stated in the Arts and Science Registration Handbook and Timetable. A Transfer credit, whether it is for a specific course on the list below (eg "RLG100Y1") or is a generic credit (eg "RLG 1**Y1"), must be approved by the department in order to count towards the writing requirement. Please contact the department for approval. In order to accept such a course, we must assess the role of written work in the course, and determine that it was taught in English, at an English-speaking university.
