This reflective paper explores how Extensive Reading (ER) can effectively prepare learners for academic tests, specifically IELTS and TOEFL. Drawing from my experience as an educator in Mongolia, I reflect on how incorporating ER into test preparation programs enhanced students' reading comprehension, vocabulary acquisition, and overall language proficiency. This approach not only improved test scores but also fostered positive reading habits and reduced test anxiety. By selecting graded readers relevant to academic topics, students engaged in meaningful and enjoyable reading experiences. This reflection discusses practical strategies, challenges faced, and observed outcomes, highlighting the impact of ER on student motivation and performance. Educators will gain insights into integrating ER into their own test preparation curricula.
