I tutored math and science throughout high school in subjects ranging from Calculus AB, Calc BC, chemistry, and physics.
I also worked as a tutor for all subjects at a local elementary school, for 4th and 5th grade.
Aside from specific tutoring experience, I believe that you learn best by teaching others--if you can help someone else understand the material, you will have mastered it yourself! I find that I as I take a class, I also "teach" the material to fellow students. Thus, I have experience teaching others, even outside of a "tutor"
