Flexibility on odd pre-reqs? (Exa. Berkeley and OSU)

Certain schools like Berkeley and OSU have other pre-reqs like Immunology and Inorganic Chemistry. Are they flexible on waiving those requirements? I'm almost done with my pre-reqs but i'm unsure how to fit in these classes to my schedule. I'm interested in both schools. Has anyone gotten accepted into Optometry school without completing one of the abnormal pre-requisites required by a school?
