Course Overview
This course focuses specifically on the range of remedial technologies that are available and provides students with the skills to apply appropriate technologies in given situations. Discussion on the techniques to monitor and evaluate performance of the selected remedial options are also included. Since this is the final course in the series, this course also focuses on integrating the material from the first four courses.
