Honestly, it makes more sense to try to graduate from college earlier by taking more credits at once rather than high school, because it makes no difference financially in high school unless you go to a private school, while fewer years of college means saving money while fast-tracking towards your career. Still, if you really want to get where you're going sooner and think you'll be ready for college next year, go for it.
skipping grades is only beneficial if you can keep up in both the academic and social senses, in my opinion.
i was supposed to skip a grade in elementary school, but i didn't want to since i am already young for my grade, and i preferred to stay with people closer to my age group during that time.
See the bolded part. My mother skipped two grades in the middle of elementary school, but she and her parents refused to let them skip her any farther ahead because she could handle the academic aspect of it but was made into more of a social outcast with each grade skipped. I guess that hasn't been a problem for you so far, though. Skipping grades is rare in the county I live in. They tend to try to meet different academic needs within the same grade level rather than just moving the more advanced kids up, and the special centers for gifted kids make everyone in the class skip years in math and do more advanced work while keeping kids of the same age together. High schools especially don't skip grades, different students can take different classes depending on the level they can handle for each subject.
I knew a guy who was two years younger than everyone else in our year when I was in elementary through high school and there were some awkward things for him, such as not having anyone who really felt like a complete peer until the freshmen two years behind us started high school and he wasn't one of the least developed and desirable (from a female standpoint) guys in school anymore. I don't think that part would be as bad for a girl, though, since it's not so obvious (your voice isn't still changing and your same-sex peers aren't starting to dwarf you, and guys care less about dating younger). That and he had to take drivers ed with everyone else two years before he could actually even get his permit. In college the most common situation that might be annoying would probably be not being of legal drinking age until two years after everyone else. Still, he seemed to do okay, and because we went to a school of over achievers he wasn't the only one who had skipped two grades.
Most of the people I know who only skipped one grade--and there have been many--skipped early on in elementary school (e.g. kindergarten or first grade) and it made virtually no difference to them, though.
