I'm going on 23 and still have no idea what I want to major in. None of my parents went to college so it's been a tough road. I do know that I completely love science; Biology, Chemistry, Physics all of it. I've tried majoring in business but no matter what I just can't pull away from science I love it too much. I've recently flirted with the idea of becoming a doctor (surgeon because I love fixing things especially the human body) but I have no idea what I'm in for in terms of financial, can I handle the blood, the long hours, am I academically suited for it etc. I currently have a 3.0 GPA I put in a decent amount of studying but I can definitely try a lot harder. If I were to apply to medical school could I write in my essay that I didn't know I wanted to be a doctor until I came to college and started taking science classes seriously and prove it with an upward GPA trend? Also are there any good sources like websites and personal quizzes about whether I can handle being a doctor or not? Thanks in advance.
