Was very challenging to understand the prof from language barriers, was either yelling or mumbling while lecturing, never responded to emails throughout the entire semester and had difficulty answering questions after class.

Took his CHEM 112 course as a first year student and was very happy with the outcome. Pearson would show up every class very happy to teach. Although he was difficult to understand at times, he made sure that students understood the material. He would often go over examples in class for students to better understand concepts. Overall, great prof.
