Step 1
Take lots of science classes in high school, including biology, chemistry, physics and advanced mathematics. Become as computer literate as possible.
Step 2
Maintain a high grade point average.
Step 3
Ask your high school guidance counselor to help you get a list of colleges that are known for their marine biology programs. (Try Marine Biology Web at life.bio.sunysb.edu/marinebio/mbweb.html.)
Step 4
Send for college catalogs and applications well before your senior year. Make certain you meet the requirements before you apply for admission.
Step 5
Choose your college carefully, especially if you have a particular emphasis you would like to study. However, realize that your undergraduate studies will be mostly biological science courses that are meant to prepare you for your advanced degree.
Step 6
Apply for summer internships in your area of interest.
Step 7
Decide on your eventual specialty in marine biology before you begin to apply to graduate schools for your master's degree. It is pointless to apply to a school where your desired concentration does not currently exist.
