I completed my undergraduate studies in 2016 graduating with a Bachelor's in Arts majoring in mathematics and economics. Following my graduation, I joined the teaching profession while still tutoring on online platforms with various tutor companies. During this time, I taught at high school and junior college students. I have continued to do so to date where I have taught in various subjects, key among them being mathematics, economics, business, philosophy, history, criminal justice, business law, anthropology, essay writing among others. I have also gained vast experience in the various styles of writing and I can strongly deliver quality work in APA, MLA, Chicago/Turabian, and Harvard. One of my critical guiding principles has always been to deliver grammatically accurate and plagiarism-free work and I always endeavor to do that as well as teach students how they can achieve such levels in academic quality. To date, I am confident to say that hundreds if not more than a thousand students come back with an expression of satisfaction and I boast of sparkling reviews whenever I have been given an opportunity to tutor.
