Stand-alone courses are offered by The Open University of Sri Lanka (OUSL) to enable those who wish to obtain more information & additional knowledge in a specific area without having to register for a complete programme of study. In pursuance of this general objective, the Faculty of Natural Sciences announces and makes available the Stand Alone Courses in Science. Prospective applicants are reminded that the OUSL adopts open and distance learning (ODL) study system which involves a minimum of regular face-to-face classes. Open University courses are therefore ideally suited for employed persons. The minimum age for enrollment will be 15 years as of the last date of receiving applications.
