To make sure exams are up to date with the latest research in language learning and teaching, Cambridge Assessment update them regularly. A2 Key, A2 Key for Schools, B1 Preliminary and B1 Preliminary for Schools have undergone a thorough review to ensure that the exams continue to remain relevant to the needs of schools and learners.
The changes will come into effect in 2020 and more information on the changes made can be found on this website – https://keyandpreliminary.cambridgeenglish.org/
To adapt to these changes, Cambridge University Press have published new editions of Compact, Complete and Prepare, as well as a brand new exams course, Open World.
