C21 Academic Skills is a downloadable set of materials for students who use English in an academic context. It develops study skills and life skills from the C21 English for the 21st Century course, adding much more detail and completely new areas of focus relevant to the academic world. There are 96 individual skills, each including a lesson's worth of succinct, focused study materials. Every skill includes three components:

• Factsheet – gives information about the skill, including the academic context, key features and examples of its application.
• Worksheet – contains exercises for practising and developing the skill.
• Teacher's notes – gives teachers all the information they need to teach the material, including answer keys and transcripts.
