Mr. O'Connell

Mr. O'Connell, full name Casey O'Connell, is a chemistry teacher that teaches Chemistry and Chemistry H at Gunn High School commonly known more for out-of-pocket jokes than teaching chemistry. Most students consider him to be a worse Chem H teacher than Dr. Mellows since he usually does not teach the content in depth and students are more likely to get a B in his class since the test category takes up more of the percentage of your grade.
