Written by a former high school Spanish teacher, Cuaderno does what your Spanish teacher would do if he or she were with you when you are trying to read or write as a Spanish I or Spanish II student -- gives you the information you need about verbs, like who's doing the action, what the tense is, what verb it came from, and so on. If you see a verb but can't remember what it is (something like "hizo" for instance), Cuaderno can tell you everything you need to know about it. If you're not lucky enough to have a TPRS teacher for Spanish (which would mean you really KNOW the verbs!) Cuaderno is the next best thing when you're reading or writing. Registered users can add their own verbs to expand Cuaderno beyond the verbs most commonly taught in the first two years.
