Immatooki, I don't know how you can find the time to play, but good luck with both the game and the test! I can't even imagine how tough the prep must be and how dedicated have to be to choose this path. (I have a DD who is planning to start studying for the MCAT soon, and that big pile of books looks intimidating. I'm guessing that what you are working on is somewhat similar).
After building the cottage, Doc has a short task, and then another, longer one that I think lasts for 6hrs. I hope that's it for the first part, but as of now I don't have the "welcome Sneezy" task yet, even though we can theoretically start getting his items in 12 hrs.
