If you are caught, you will be expelled and it will go on your

school record. It may haunt you if you ever decide to enter a

college.



In addition, your lack of education will catch up to you. When

it does, life as you know it at that time will come crashing

down around your feet.



Its unfortunate that when video games are sold that there isn't

a warning about ';Life is not a video game!'; Most kids today

think they can cheat their way through life as if it were a

video game by just using a cheat code.



Life has no cheat codes and no shortcuts. Those that try

to cheat life or take shortcuts usually find out that life

takes no prisoners and allows no one to cheat their way

to where they want to go in life.



Two of life's rules:



If you can't earn it, you don't deserve it!



No cheat codes allowed.How do i change my grades on this website?
Hmmmm I would try working at school.
You study and do well in class. That's how you change grades. And if you try to hack, it's a crime, and could land you in jail. It's happened to high-school students.



In short:



1. Study!

2. Do well in class!

3. ????

4. Profit!
