I am an active educator and professional tutor with substantial experience in Biology and General Science. The past two years I have been tutoring online intensively with high school and college students. I have been teaching for four years and this experience has helped me to hone skills such as patience, dedication and flexibility. I work at the pace of my students and ensure that they understand.
My method of using real life examples that my students can relate to has helped them grasp concepts more readily. I also help students learn how to apply their knowledge and they appreciate that very much.
