I sent a fake 'unacceptance' email from my top college because I wanted to go to another college.
Have you done this for a different college?
I haven't done it to any major college before
Wanting to go to a particular school is okay, but lying about not getting in to another so that you can go to the one you really want is not okay. Lying to your parents is not good and if they find out they will not trust you again.
I'm a good liar.
You should search your motives and find out what school you really want to go to. Lying isn't going to get you into the university that you want, especially if they notice that you been forging false material. Apply for your first pick and let your qualifications speak for themselves.
