What do i need to join the u.s marines?

First off im not trying to be a dick but you need to have your facts straight before answering, a year old knowledge wont apply here. Secondly i have a new tiny phone so sorry if i misspell, its very hard to correct it all. Okay so i went to a army recruiter and he told me all i need is my ged (because i havent graduated high school and im not going to go to deep into it right now) i need to lose a bit of weight and bring him my medical records. Btw i cant see the writting anymore because of the keyboard. The weight for the army at my height (6ft) is 200. I didnt get to talk to a marine corps recruiter because there office was closed. This came as a suprise to me because i had emailed the army and a man told me i had to go to community college to earn semester hours to be considered a high school gradute for enlistment purposes. The recruiter said i didnt have to and the requirements are always changing. Anyways whats the deal with the marines? Is there anything extra that i have to do with a ged? I know you have to score a bit higher on the asvab with a ged, if it matters im trying to go infantry rifleman 0311. Information for sites such as military.com is all outdated and wrong. Thank you for your time, also if some are confused about the whole ged thing (heard you cant get it when your over 18 not sure if that’s true) im 17 turning 18 in 6 months. My heart is set on the marine corps but i feel like id have a better chance at joining the army.
