haha fixed! I'd forgotten what my title promised and got sidetracked. also added leben as an option for live--I think both may be attempted, and did my best to include other options with the other verbs. thanks for the input & let me know if you spot anything else!
only accepting 'muessen' and 'fuehlen' and not 'müssen' and 'fühlen' is absolute nonsense. What decade is this supposed to be from? Maybe put a disclaimer that for some reason you've decided to mix pre- and post- spelling reforms in your answers.
You should accept Umlaut for all words, not only for some (not accepted are feel=fühlen, must=müssen).
A better translation for to get is bekommen (kriegen is not proper German).
clean/tidy - aufräumen, säubern, reinigen
last - halten
get/obtain - erhalten, bekommen (and many more depending on context)
reach, pass - erreichen (in the sense of "could not reach you")
use - gebrauchen, benutzen
lernen for study is ok (as would be studieren), but studieren for learn rather not
Cheers
