I am Chad Bergman, a current Dartmouth student pursuing my Bachelor's in Economics with a physics minor. I have experience tutoring college economics in person on Dartmouth campus as well as online tutoring in high school calculus and physics. I've had great success on the SAT and ACT as well as my AP tests in high school, and I hope to help others succeed as well. My favorite subject to tutor is physics because I feel like learning to apply a few fundamental principles to different real world situations is extremely useful in any discipline. While tutoring I try to help students master the fundamentals so they can apply them to the material we're working on as well as future material. Outside academia, I help look after my four siblings and play more League of Legends online than is perhaps healthy.

I am interested in Physics and Mathematics and working out practical problems from plumbing to electronics. I will someday go back for my Ph.D. in Physics but until then I am looking to grow as an engineer or computer programmer.
