You will be expelled if you are caught which will go on your

school records.



In addition, its really not worth it. If you can't earn the grades

now, you'll never make it in the future. Your lack of education

will catch up with you and you can only cheat your way through

life so far before your lie crashes down around you destroying

your life as you know it at that time.



One of life's rules: If you can't earn, you don't deserve it.



Life is not a video game as kids today seem to think. There

are no chest codes to win at life as with video games!How do i get into the school districts website to change my grades?
Hope this Helps is right.

I couldn't have said it better.

Why didn't your parents teach you any better than this?
