If you've completed the entire De cabo a rabo series, you won't skip a beat. If you've been studying Spanish elsewhere for a few years, you're in for a treat. Either way, you have a solid foundation in the language and are ready for new, advanced challenges, and that's where Al fin y al cabo ("when it was all said and done") comes in. But this time around, as in life, there are no units, there are no limits.
