This study attempts to replicate Pawlak's (2018) Grammar Learning Strategy Inventory (GLSI). It explores the use of GLSI by Saudi students of English as a Foreign Language (EFL) in their college preparation year. The re-emergence of GLSI after a long period of neglect is a significant development in Language Learning Strategies. Consequently, due to the shortage of GLSI studies in Arab countries, this study was conducted. Participants were assessed using the GLSI with its four categories of metacognitive, cognitive, affective, and social strategies. 419 EFL students participated in this study. The findings generally showed a high use of grammar strategies in all four categories of GLSI among EFL learners. As a result, a strong, positive, and significant correlation was found between all the categories of strategies. Furthermore, students' Grade Point Average (GPA) did not appear to affect their use of GLS.
