I started tutoring at home with my younger sister. She's always had problems with math and science. When I tutor, I try to level myself with my tutoree and use analogies to help them. I have also tutored a couple of high school students but not without the help of my classmates too. It's always better to learn not just from one person because others may have their own understanding of the subject or topic and their way could be much easier for you to absorb.
