Hi Lisa--
We had a similar problem getting all our classes in too. Our agency actually gave us the book (STEP) and we were able to complete the classes at home on our own time and turn the tests into them. It might depend on the state your in as far as the in-class requirements.
If your recruiter told you it would be okay, then in good faith they need to honor that. Speak with the boss. If there is still a problem, get a copy of the homestudy itself and go to another agency that is willing to work with your time constraints. BTW: If you need the ammunition, remember that private agencies are licensed by your state.
