My understanding is that the concepts of physics that are most relevant to anesthesia practice are those that deal with the gas laws. This set of concepts is covered in physics 1 at my school.
Having said that, do you think it would be necessary to re-take physics 2 next semester? If I decide not to re-take it, won't the admissions committees wonder why I was willing to re-take physics 1 but not physics 2? My number-one choice for AA school is Emory.
