Hi! I'm from Pennsylvania in the United States.
I'm not the quickest learner, and I know school can be too fast-paced, so I like to come here to help people get through it, or get ahead, or satisfy curiosity!
I'm in college physics and computer science programs, excelling more at computer science grade-wise because it hasn't gotten tough yet. But I think I have more physics knowledge, since I get more experience with physics.
Both of those require math, so I can also help with some math stuff!
And I love the OpenStudy feature that lets me type equations and draw!
