academic dishonesty

hi all. i am a triple qualified candidate with a nom. this week, my ap chemistry teacher and i had a talk about one of my homework assignments. i took previous textbook work and replaced the title with a newly assigned chapter name and problems, and turned it in. we both talked privately, i apologized, and gave our views. i tried to compromise with him, but what he states is true: there's a system and he has to follow it.
For our first offense, we receive a 0 for the assignment, get our final semester grade lowered by a letter grade, and i believe it goes on our academic record (not transcript)

obviously, i feel bummed b/c of this stupid mistake and i realize that at the academies and as officers, i can't do this ever again. i feel lost.

my questions are:
what should i do at this point?
should i notify admissions and my MOC?
how badly will this hinder me in admissions?

This was a really stupid thing to do, of which you are now fully aware. Learn from it and move on. You are not sworn to an honor code at this point, so there is no need to self report. Let it be a reminder that sometimes teenager do stupid things. In the future, don't do stupid things. Just my opinion, FWIW.

^^^ I agree with Mom3boys (and good luck with that mom!). Just learn from it and move on. You're already paying the price. It's awfully easy to let yourself get into trouble in high school. Just make sure it, and any other potential troubles, don't happen again.

Sworn to the honor code or not, it is sometimes better to be honest with things like this. It looks better for you if you told the academy yourself, rather to have them find out about it later on. This is like the Drug Abuse thing... lets just say from personal experience that being honest about things that affect your integrity doesn't always put you in a bad light. As a matter of fact, it might even help you, because they see that you are mature enough to take responsibilities for your mistakes. But this is your call, report it if you feel strongly enough about it.
