This study aims to investigate the undergraduates' satisfaction with their EFL learning outcomes attainment regarding the four English skills: listening, reading, speaking and writing; and their perceptions about learning activities and assessment tasks implemented in the classroom. The participants of the study were 391 fourth-year students who took different academic disciplines and completed the five courses of General English (GE) at a university in Vietnam. The instruments employed to collect data of the study were closed- and open-ended questionnaires. Both descriptive statistics and content analysis were employed to analyze data. The findings of the study revealed that about two-thirds of the undergraduates were not very satisfied with their learning outcomes, and that those students did not have positive perceptions about learning activities and assessment tasks implemented in the classroom. The study also made some recommendations to improve the quality of the implementation of the EFL curriculum at the university in particular and at the Vietnamese tertiary level in general.
