In high school, I was dually enrolled at Ohio State University starting my sophomore year. I took courses in English composition, History (modern European & American), Science (biology, chemistry), and Calc 1 (my junior year of high school).
As for my ability to tutor for the ACT, I took the ACT twice as a high school...
I have 5 years of experience in most subject areas and grad levels 4-9, and have experience tutoring high school level math and English. I can help with Test Prep and Science as well, both creating and implementing study plans for success.
