The B1 Preliminary exam, formerly known as Cambridge English: Preliminary (PET), is an intermediate-level English qualification that shows you have mastered the basics (Reading, Writing, Listening and Speaking) and can use English in practical, everyday situations.
It is designed for learners who want to read simple texts, write emails and letters on familiar topics, and communicate effectively in spoken and written English. Preparing for the exam helps you develop the skills to understand opinions, express feelings, and handle real-life tasks in English.
The B1 Preliminary exam is the logical next step after the A2 Key exam and a solid foundation before the B2 First exam.
