I'm thinking of saying that I have a school degree that I did not earn
Why would you claim to have a degree that you did not earn?
I think lying about it could help me out.
You should be honest about your education and the degrees that you have earned. You should never claim to have worked for and earned a degree that you did not really get. This is lying and deceiving others about who you really are.
Who cares.
You could get into a lot of trouble if you aren't honest about it. You should just tell them your real qualifications.
