Math & Science


Chigozie Nwoke, PhD (in progress), BS

Math (6-12), Test Preparation (quantitative) 

Chigozie graduated from the University of Nigeria with a first class honors degree in mathematics. He has applied his love for math in a business setting, to streamline and optimize operations, but has returned to the advanced study of mathematics at the University of Pittsburgh, focusing on algebra, combinatorics, and geometry. In his prior teaching experience of middle and early high school students, Chigozie worked on fundamentals by breaking down problems in new ways, to help his students develop their own “style” of problem-solving. Now, as a volunteer and as a tutor, he does the same, helping students to practice skills, see problems in new ways, and unlock mathematics through an understanding of fundamentals, whether teaching algebra, geometry, or calculus!
