how bad will a no pass class affect my chances of getting into pharmacy school?

Hi guys,

im currently a first year at UCSB as a Chem major and I was wondering how bad a no pass class would affect my chances of getting into graduate school for Pharmacy. The class I’m getting a nopass in is linear algebra which I believe was really easy but due to the fact that I accidentally kept it as a Pass/No Pass class (its the last major requirement of math for Chem), I have to fail it in order to take it again next quarter as a Letter Grade. I have talked to the student advisors of my college and they rejected my petition to change it to Letter Grade since it is way past the deadline to change the grading option for classes (the final for it is in 4 days). I was also wondering how much a D or a C- would affect my chances of getting into graduate school. Any help would be great! Thanks:)
