First, make a 4-year plan.
This is a marathon, not a Sprint. Those who make it to the finish line don’t rush. You have to be steady, methodical.
First in that plan: keeping a 4.0 while in CC, taking as many non pre-med pre-reqs as possible while in CC, making sure you take the classes required by your flagship.
What classes have you planned for your first year? Any summer class?
What sort of part time job do you have - can you work as an EMT, CNA, anything where you’re in contact with underserved populations?
Plan to take the MCAT spring of senior year, and work in a research lab after senior year, called ‘glide year’.
Find a good backup major (biostatistics or bioinformatics would be right up your alley if you’re into math).
Stay in shape. Sleep enough. Avoid alcohol-fueled parties - find other ways to have fun. Becoming a doctor will require you to stay healthy. (Broomball, yoga, hoops, laps, Zumba, whatever you like).
