The practice books El cronómetro are designed to prepare for the different levels of the Diploma de Español como Lengua Extranjera (DELE). The five areas of the exam - listening comprehension, reading comprehension, written expression, oral expression, as well as grammar and vocabulary - are practiced in these workbooks with the help of the included audio CDs. This is done through exercises that authentically replicate the exam tasks. Additionally, the constant monitoring of processing times raises awareness of the efficient use of the limited exam time during the DELE tests. Useful information about the exam process is also provided, and phases of learning reflection are integrated. References to supplementary learning materials guide learners through the more than 30 work units. In the appendix, learners will find relevant materials.
