About the course

The fundamental theorem of algebra is the foundation for higher level math. This class will explore multi-variable functions and the basics of trigonometry; this translates to understanding rates, building foundational knowledge for STEM courses (in proportions, data interpretation, etc), developing critical thinking skills, and covering a portion of the math questions students will see on the SAT/ACT.

Hello! I'm Beth and I recently graduated from Northeastern University in Boston with a B.S. in Chemical Engineering. I currently work as the materials and chemical engineer at a startup in the Boston area that works on remediating industrial mining waste. I have been tutoring for nearly 8 years, starting back in Columbus, OH where I helped at the Metropolitan library, and spanning into college at the Connections Lab at Northeastern University. My favorite part of tutoring is helping students reach their full potential and get them to those "AH HA" moments.
