Soon after graduating with a Master’s in Literature from Southern Arkansas University, she joined an institute as an English language trainer. She has had innumerous student interactions and has produced a couple of research papers on English language teaching. She soon found that non-native speakers struggled to meet the English language requirements set by foreign universities. It was when she decided to jump ship into IELTS training. From then on, she has been mentoring IELTS aspirants. She joined IELTSMaterial about a year ago, and her contributions have been exceptional. Her essay ideas and vocabulary have taken many students to a band 9.
