This research attempts to add to the existing literature of language learning strategy uses by advancing our understanding of what language learning strategies (LLS) are preferred by learners who were given a one-year English education at two state universities and to find out whether strategy uses were directly related to being successful in language learning. A total of 286 students filled out a questionnaire called Strategy Inventory for Language Learning (SILL), participated in the study. For deeper information 6 students from each university were asked to answer interview questions. It also aimed at discovering what strategies the students mostly preferred and whether there were any changes in strategy choices at the end of the learning program. The results of the study showed that there is a significant relationship between students' language learning strategy use and language learning levels. In addition, in the pre-test post-test comparison applied to see the possible effect of the preparatory education, it was observed that there was a positive increase in the use of language learning strategies by the students at the end of the preparatory education. Based on the results, the study is expected to contribute to the theory behind language teaching and learning in Turkey. Keywords: Language proficiency, Learning strategies, Preparatory education, University students, Turkish learners.
