Having graduated with a bachelor's degree in Natural resources management in 2016, I followed my passion for being an impact to other people by sharing my knowledge with the rest of the world. I joined online tutoring and academic writing where I have continued to do so to date. During this period, I have worked with various academic writing and online tutoring sites. Some of the companies I have worked with include FreelanceWritingCenter, QualityWriters.net WritersHub, and Chegg tutors. Besides, I have tutored in a number of subjects primary among them being environmental science, natural resources management, human resources management, Geology and geological sciences, business courses, criminal justice, criminology, psychology, philosophy, and history, In all this, my greatest strive has been to see students gain skills necessary to achieve their life goals, help them overcome intellectual challenges and ultimately see them excel in their weak subjects. Consequently, I have learned how to handle students of diverse intellectual abilities and impart then best of study skills and problem-solving techniques in them.
