I am a sophmore, majoring in Biology with a Minor in Chemistry. I have a 3.8 GPA and am almost 50% done with my degree. I have 51 hours at school. I have almost no hours shadowing but i will start doing that soon. I plan to go ahead and start going over some stuff for the MCAT, would that be totally useless?. i just need to get on the right track of things to make sure I hopefully get into medical school by the time i am 22. Anything would really help. I just need to see what all needs to be done from here on out! I have also heard that sticking to things for long periods of time shows your dedication to certain things rather than changing all the time. Would having the same job for 4 years help?
