Is there a way to become a marine corp officer with an SAT score lower then 1000?

No but if u were in rotc or some military based program for the 4 years of high school. U can run through traditional boot camp then affter tht most likely go to camp penalton dependin on ur pattalion and location and go through rifle training and after the total of 4months and one week of training ull be private first class . Also if u go through 4 year college u can enlist an officer autimatically.
