Hi Ashleigh,
If you have a specific question, there are many people here who can probably give you the answer you seek, but a generic "give me some info" request on the United States Coast Guard Academy can best be fulfilled at
www.cga.edu
I would recommend you first browse their website:
read the cadet blogs,
learn about the areas of academic majors,
read about the athletics,
learn about the admissions process,
learn about AIM, about Eagle summer cruises, about Swab Summer,
read about the missions of the USCG and the options after graduation--
it is full of helpful info. Then come back and ask anything you want to clarify, and I'm sure someone will help you. There are current cadets, former cadets/active duty, Admissions Partners, Admissions Officers, parents, and future swabs here all waiting to help you!
Good Luck!
