I second the suggestion to take the MSF Basic Riders Course. It took a whole weekend up between classroom and course, but I actually had fun with it, between the other folks in the course and the instructor. Not the worst way to spend a weekend.
Regarding test questions - I'm in Wisconsin and maybe Tennessee is different, but up here the test questions are honestly pretty easy if you take the time to read the DOT manual. At least here, they don't ask a bunch of obscure questions, they want you to know the practical stuff, things like traffic laws, proper lane position, safe operation techniques, etc., things you probably need to know anyway. If she spends a few hours getting familiar with and understanding the state motorcycle manual, I'd imagine she'd have no problems.
