Hi everyone. A few years ago I took an Intro to Biology course on a pass/fail basis. At my school I have the option of switching it back to a letter grade, however this would lower my GPA to under a 3.0. I am trying to decide if I should just take the class over or put the grade that I already received on my transcript and then get better grades in the higher level biology classes. Do optometry schools discourage repeating courses? Thanks for any advice.
