Grantham University did not give me a degree that is worth anything to employers. Their credits don't transfer to 99% of other schools that I applied to. The few schools that they say will accept their credits only accept a few. Basically, any classes you take there are worthless in the eyes of major universities if you ever want to transfer.
It does not seem to have regional accreditation, which is important. You are better off going to a real school. A school that will give you a degree that employers will respect or just save your money and shoot for trade schools where you can really get a job when you are done.
