I always read these types of posts and told myself I would never post one. However, as time passed, I have concluded I simply have no idea about my chances. I was hoping you all could give me some insight as to what you think! 
I am a Senior from Texas (white male) currently working on my application for Emory ED for the class of 2022.
GPA: 4.0 UW 4.29 W
APs: Chemistry (11th), English Language (11th, receiving a 3:/), Physics (12th), Spanish (12th), English Literature (12th)
Dual Credits: US History, Biology, Calculus 1 and 2, US Gov and US Eco.
ACT: 29; 30 super score.
SAT: 1340
Extra Curricular: Marching Band (Head Drum Major), President of Science Club, Founder and President of Yoga Club (I teach classes for the school and community), NHS member, Spanish Honor Society Member, Vice President of Robotics Club.
I attended Texas Boys state over the summer, but have not completed any summer research programs.
Work History: Started a business when I was 10 raising ball pythons. I sold the business when I was 16 and started freelance article writing for a Naturopathic (yoga and natural medicine are two of my passions and are also what I plan to write my Common App essay about) Fertility Coach and wrote blog articles about certain therapies to help patients suffering from infertility.
I plan on majoring in Neuroscience (and possibly double major in Philosophy) and then attending Medical School.
I like to think I may have a chance, however, my concerns lie in the fact that 1) I am white 2) I am a male wanting to enter the STEM fields 4) I am middle class and 3) I am from a small school, so it doesn’t offer as many classes as others (I have taken all the upper-level classes my school offers, and all the DC classes I took were because my school didn’t offer the AP counterpart). Could this affect my chances at all? I also realize that my scores are in the 25th percentile of applicants, so that is another aspect that may bring my application down.
I want to attend Emory because it just seems like a perfect balance of school size, prestige, school spirit, research, and location; Atlanta provides so many opportunities that would just be amazing.
Also, do you all agree that Early Decision is the best option for me? With it being my first choice? Does ED provide any benefits other than being notified earlier (i.e acceptance rate)?
Other schools I plan on applying to:
Johns Hopkins
Vanderbilt (both of these are stretches, I feel, along with Emory)
University of Texas at Austin
Univesity of Washington in Seattle
Thank you all for your time! I appreciate it immensly!
