The chemistry major requires 45 semester hours in chemistry. Students must declare their major by the time they have completed 60 semester hours. Transfer students must take at least 14 upper division chemistry hours, including CHEM 4128, 4518 or 4538, in residency at the Downtown Campus. A student who has declared a chemistry major at UC Denver may not take additional chemistry courses outside of the department for the purpose of applying those credits toward meeting the requirements of the major without prior written approval of the undergraduate advisor. Normally, no more than 3 additional hours of transfer credits will be allowed. The minimum grade in chemistry courses is C- (1.7) and a minimum chemistry GPA of 2.0 is required in chemistry and ancillary required courses.
