English-medium instruction (EMI) programmes have become more and more popular in Vietnamese higher education. Previous studies have reported a number of challenges that students face in their EMI learning journey, underlining the necessity to develop appropriate learning strategies to complete their programmes. Accordingly, this study focuses on students’ learning strategies in three EMI programmes at a university located in the centre of Vietnam. Data was collected via focus groups with 20 students and then analysed based on thematic analysis. The findings show that students employ different learning strategies which can be classified into three groups: before class, during class, and after class.
