Not much. Since the focus of CWRL courses is studying English composition and/or literature, we do not ask for much prior knowledge of computers or software--just some familiarity with common word processing programs. In fact, the CWRL is often a good place to learn other computer skills. Although classes vary in the teaching and use of available software technology, students taking CWRL courses are free to learn any of the wide variety of programs provided on CWRL machines during the CWRL's open hours.
