The Textbook for Sowieso has few exercises. It is however loaded with "Aufgaben", i.e. critical thinking tasks. The practice exercises, necessary for cementing new material into our store of learned knowledge, are found in the accompanying workbook. It's recommended that each student have his or her own copy of the workbook, in which to practice and take notes. Also included are learning strategies, introduced where they are most relevant, and a concentrated reference grammar.
