I have been teaching students in the public for more than 8 years now. It is so fulfilling as a teacher to know that your students have learned massively from you in any subject area since I specialized in general education. While having time off from face-to-face teaching due to pandemic, I endeavored in tutoring students online who specifically need assistance in English and Writing. As a former CourseHero Tutor, I have guided students to learn basic and general skills required in answering their homework in English, Writing, Math, Algebra, Ecological Science, Environmental Science and History. Moreover, I had consistently received helpful ratings on the platform and have accumulated a general average of 87% performance as a tutor expert.
