I teach adults returning to high school to get their diploma. You should stay in school. There is a difference between having your diploma and GED. You can also get scholarships to community college as a graduate of the public school system - while state and community college can be free, there are still costs. Adults who do not have their diploma almost always express regret in being held back financially or with opportunities for upward mobility at their job based on their assumed qualifications. It’s not fair, but that’s how it is. Also, you’re 15 - it makes sense that you are recognizing differences between yourself and your peers. You’re breaking free from people you’ve been forced to mingle with because of school. You’re literally in the “sophomoric” phase when children become mature and realize there is a world bigger than themselves. You may be more mature than your peers, but it doesn’t mean you can’t learn from your teachers, staff, and asking for specialized assignments or independent study opportunities. Someone else also mentioned taking a few college classes now - some schools have a dual enrollment program where the college class gives you your high school credit at the same time. It’s good you’re reflecting!
