Then again, it's also good to not lie to your users.

I tried the French beginner course, using German as my base language. The very first items were:
1. Hallo (hello) > Bonjour (I think salut would be better)
2. Guten Morgen (good morning) > Bonjour
Then it asked me what Bonjour means, and selecting Guten Morgen is wrong, correcting me to Hallo. Then it asked me what Bonjour means again, this time Guten Morgen is correct.
So yeah, good initiative, but please just tell me what it is and don't lie.
