- The Future Workbook with Audio CD allows students to devote their time to the lessons and specific skill areas that they need to work on most. In addition, students can replay the audio portions they want to listen to as many times as necessary, choosing to focus on the connections between the written and spoken word, listening for grammar pronunciation, and/or listening for general comprehension. Future is a six-level, four-skills course that empowers learners with the academic and workplace skills they need to get ahead by helping them transition to further education or career training.
