I am working on 3 new achievements for doing well on the quizzes, and they should be out in the next update! You can look and see what they are now. You can also try to ace all the quizzes ahead of time, and the achievements unlock once I release them and you re-take and ace one of the quizzes. You can make the honor roll by getting A's and B's, Dean's list by getting all A's, or even the Valedictorian for getting all A+'s.
I have been hard at work adding new missions to the Moon and Earth. In the next update, there will be targeting missions and races on both worlds, as well as a bit of new furniture. I have discovered it is quite funny and fun to throw stuff on different worlds and see how differently gravity really impacts the result. Things behave much differently on the Moon, with its low gravity. This gives you a feel for how objects might really behave on different planets!
