I need some advice.What should I do?

If you do not want to graduate a year early, talk with your guidance counselor about other options. Your school may have half-day programs for juniors and seniors. Regardless of how many credits you have, your state requires you have have fulfilled credits in certain areas. Take more elective credits to delay graduation. Since it's summer, get a part-time job or start volunteering somewhere. Colleges also look at that. Community service is usually very important to colleges, so now would be a great time to start.
