I've been a private tutor for almost 10 years--specializing in biology and chemistry at the high school and undergraduate level. My favorite part about tutoring is seeing the "lightbulb" go off in someone's head when they finally get something they have struggled to understand before. One of the things I am most proud of is my ability to help others understand complex material. As a person who has ADHD and dyslexia, I especially enjoy working with special needs students.
