This workbook by Zdena Malá, Director of the Krystal Institute for Language and Preparatory Studies Centre, is a supplement to the publication by Lída Holá and Pavla Bořilová: Česky krok za krokem 2. It offers numerous activities and exercises for practising points dealt with in individual lessons of the textbook, with the emphasis on vocabulary and grammar. Also included are more difficult exercises suitable for faster and more demanding students, and appreciated by students from Slavonic countries. These extension exercises are designated with a + sign. All exercises, commentaries and explanations are in Czech only. The vocabulary used in the exercises and the texts matches the vocabulary for Česky krok za krokem 2. The workbook can be used not only as a supplement to Czech lessons, but also for independent home preparation and for teaching yourself. Hence the key to exercises at the back makes up an integral part of the publication.
