Is it a problem if I don't ask a pre health advisor to write me a recommendation letter. I don't think she knows me that well! I have asked another advisor to write me a letter, and I'm positive she knows me really well. So what are the thoughts??
Are you switching from one pre health advisor to another pre health advisor? I don't see why that would be an issue as long as you get a committee letter. If you're just talking about another type of advisor in your school (my school had departmental advisors, for example) I would potentially reconsider that as schools tend to be suspicious if you didn't use your school's committee letter.
