1. I have gotten a few good snippets of advice that I have applied to my life to increase my odds of getting into school off of here, but the major issue of (atleast the pre-med forum) is that it is (for the most part) students trying to give advice to other students. A lot of the members on here post as if they have made it through med-school or are on admissions committees trying to give each other advice on their own anecdotal life experiences of things they've read that aren't always based off of research regarding admissions, but rather things they've read themselves on here and have essentially turned into a big game of online-telephone.
2. The hate for alternative care providers, Caribbean schools, and the like. SDN is literally the only source that I've utilized that has such deeply ingrained hate for the two I just mentioned. Yes, I have been warned by physicians that Caribbean schools are iffy at times, but the stats I've seen here are blown wayyyyy out of proportion, you can literally take any statistic and rearrange some data to fit your own viewpoint. As for alternative providers and their specializations, on here it seems to be a consensus that they are all bumbling hippy idiots who are killing patients left and right. However in real life the doctors I know absolutely LOVE THEM. We have an integrated oncology program at my hospital that has NDs and MDs/DOs working side by side, and there is mutual respect, neither side thinks the other is misguided or filled with false medicine that just exists to make a buck. Again, as above, returning to the students-teaching-students point, most of us have never experienced it and are lecturing based off of anecdotal evidence.
3. The hypocrisy, plain and simple. I have read posts dating back a year or two, and see conflicting viewpoints regarding what is good, what is bad, what will get you into med school, and what will absolutely keep you out. I have even seen it on my own posts; 6 months ago I was told by many of you I have no chance of getting into a medical school. Then a month ago after I asked a question regarding taking my ND acceptance vs taking the chance to apply MD/ DO this upcoming cycle, I was told "you can walk into almost any DO school, and have a solid chance at some mid/ low-tier med schools". Literally the only thing that changed was that my GPA went up .05 points. There was even a flip-flop regarding my leadership in my fraternity. First it was said that I shouldn't even list that I was in one, even though it was something that shaped me into what I am today, then I was told that it is something awesome that I should emphasize.
Just my 2 cents.
