As an essential part of EFL academic practices, writing is the most required skill in higher-education context. Subsequently, the requirement of having a high command of English writing skill emerges as one of the most important criteria for qualified EFL graduates. In reality, many students are still struggling to write academically in proper way, especially in undergraduate level since they are novices to academic writing practices. As a result, writing anxiety hinders the process of academic writing that affects the quality as well as perception of writing among students. Thus, the present study aims to investigate five EFL undergraduate students' perspectives on their academic writing practices in relation to the challenges of writing anxiety. The study was conducted through the lens of qualitative case study. Two primary data sources were collected and triangulated, i.e., semi-structured interview, and document analysis. Participants' experiences in dealing with anxiety during the learning and writing process were inquired through a semi-structured individual interview, which subsequent responses are clarified through an analysis of learners' academic essays to cross-check the whole data. The findings showed that the least anxious learner showed better writing performance then those who showed higher levels of anxiety. While the most prominent aspects that learners felt anxious about were lack of English writing practices, poor understanding of grammar rules, insufficient vocabulary, and fear of negative evaluation.
