Questions I have for those who answer:
-Am I doing okay so far?
-Any advice to improve on what I have?
-Chances to get into the colleges I have listed?
-Advice on going farther into economics at an earlier age?

Disclaimer: I understand that this list of accomplishments are relatively short, I haven’t found much I have been interested in in terms of clubs and sports. I am just a naïve 16 year old seeking advice from others. Any help or information you could give to me would be greatly appreciated. Thank you for your time.
