Since you still have a year, keep doing your best to get your GPA up. I don't know anything about advanced vs standard diplomas, so I can't give any advice on that. If you don't get into your preferred school next year, take a year of community college and find an internship you're interested in.
Out of personal experience, my best advice is to take your 2025-26 year of high school. Look into more IB and AP classes, and see if there are any concurrent enrollment opportunities with your school district (they are so much better than AP and IB). Wait until the fall and see how you're doing. I also recommend talking to some admissions counselors and college students, because they've got a much better view of how graduating early will affect your college chances
