Supernova, sqwkvfr is correct, Gleim does have a method for your endorsement (they have to, because I'd never just "sign off" a student that walked up to me and said "I studied this, and am ready for the test"), and so do many of the other courses (King School's, Sporty's). But realistically, those cd rom programs cost a lot! Most flight schools in the US offer a one time fee for the ground school portion which in some cases is half
what you'll pay for those learning aids, plus you'll have to added benefit
of being able to participate in classroom discussions (try asking your computer a question and see if it responds
), and get to know your flight instructors. The choice is up to you of course, just my 2 cents worth.
