The RCA student workbook was first authored and published in May 2002 by Sabbir Hossain, to replace handout and individual worksheets. It is subject to continuous update with the latest exercises. There are comprehension questions from video material shown in the course. A video account of a young man, David, produced by Sabbir Hossain has been particularly well received, and there are questions upon 'David's Story' in the workbook.
