<p>what are you asking?
on [UC</a> Davis General Catalog | Chemistry (CHE) Courses](<a href=“http://registrar.ucdavis.edu/UCDWebCatalog/programs/CHE/CHEcourses.html]UC”>General Catalog - Welcome) chem 1a doesn’t exist.
chem2a is required by most majors at ucd… soft/hard sciences and engineering, basically.</p>
