Your SAT’s are low for Dartmouth. Keep in mind that the averages include scores for “hooked” applicants as well (ex. recruited athletes, legacy etc.).
It is fine to put in some reach applications but be sure to create a well balanced list that also includes match and safety schools that paper affordable and that you would be happy to attend. Thus far every post you have on CC is for a school that would be a huge reach given your SAT’s (ex. Yale, MIT, Dartmouth). I’d suggest that you spend some time focusing on match/safety schools.
