The Office of English Language and Writing Support (ELWS) has set up a wide range of free non-credit courses for graduate students. They offer practice and instruction in the types of oral and written communication done as part of graduate programs. Some courses are intended specifically for non-native speakers of English. Look at the course descriptions for the full range of courses (and workshops) that are offered. Check to see what is currently being offered, or look at the course schedule for the entire academic year. Choose the course that best suits your needs, and sign up fast -- spaces are limited!
