During the 2024-2025 academic year, the State of Oregon enacted rules to keep all majors level chemistry classes taught at public institutions equivalent... and after considerable discussion, the CH223Z / CH229Z system was born.

At Mt. Hood Community College, we combine CH223Z (the 'lecture' portion) and CH229Z (the 'lab' portion) into a single class with a single grade to avoid student confusion.

I will refer to both CH223Z and CH229Z as simply 'CH223' or 'Chemistry 223'.

For additional questions, please email the instructor, Dr. Michael Russell.
