Does my year in college invalidate anything that I've said? I've shadowed physicians before. The idea that the physicians I shadowed could write anything substantial enough to put on a medical school LOR seems ludicrous to me.
I guess they could write some BS, but I would never shoot myself in the foot and submit one of those "he's nice" letters.
Yes, but how can a physician you've only shadowed make those claims?
"Promising student?" - you shadowed them, not took a course under them.
"Have a gift in regards to medicine/patients/ a certain specialty" - How can they tell when you just follow them around and stay quiet when they're dealing with a patient? They certainly cannot tell if you have a certain knack for a specialty by just following them around for a couple of days.
"Knowledge" - WHAT. You're a pre-med. ANY knowledge a pre-med has on medicine is made irrelevant and insignificant once one reaches medical school. If one premed knows 10 things about medicine and another premed knows 100 things about medicine, we learn in basic chemistry and physics that both are about equal to each other (significant figures) when comparing it to the millions of things one learns in medical school. Thus, there is no advantage to having "knowledge about medicine".
"Knack for radiology" - This is absolutely absurd. First, many people change their minds once they reach the medical school level. Second, there is no way someone who you only follow around can possibly tell if you have a knack for something like radiology.
