Graduate early?

Im 15. I go to a private high school that opened up for the first time this scholl year that just passed. Only freahman were in the school. I have more credits than I already should and my counceler said that if I wanted to skip a grade all I had to do was take 3 credits of noght sckool and I’d grauate at the end of my junior year. But that means I’d have to transfer from a county school. I know I can do it and I know it’s going to behard to keep up wit school but I now I’ll handle it.I dont like my school that much now cause private schools are really strict with grades as well and if I tranfered to a county school I know I’d be more comforble. Anyway people say that im being stuid that high school is the suppose to be the best time of your life and if I am always working in schoo that I’ll liss out on a lot. Like sports and stuff. My counceler aid I would have the chance to go to prom. I would be able to chose if I want to go to jr or sr prom which eer I want cause I’d be a junior and cenior at the same time. I could even go to both proms and I also would be able to go on the senior year trips. Also I want to transfer cause..maube I’ll meet someone special at my new school that im loking for. I want to leave my current school but yet I donmt want to. should I skip a grade?and my counceler told me it would look reeeally good on college applications (cause im already worring about college) and that colleges like that but also some people say that it might not really work cause I may skip a greade but all my grades may be just passing. Cause it’s hard to ace all classes while aking 1/2 more then average. Sould I or should I not?
