All the best for your important math test and the whole second year of nursing school!! I am keeping my fingers crossed that you will be able to beat the 88%!!
Two trip planning comments (after all, that is the whole reason why we are on the DIS...

)
1) I don't think there is a bus from Boardwalk to the front of Epcot. There is one from DHS, but not sure it would run before rope drop. When we were staying there there were conflicting infos as to where people were being hold for rope drop (at IG or in FW). But since then the whole rope drop system changed quite a bit (some parks went to not opening the turnstiles until opening time, so really no rope being dropped) and then back to a real rope drop. I found the people on the Boardwalk Resort FAQ most helpful for finding out the best rope drop strategy!
2) I just noticed that indeed the Night Time Safaris (Kilimanjaro Safari open in the evening) are supposed to start in spring 2016 and so is the new AK night time show. You might want to keep that in mind with your itinerary planning. I could imagine that this means that AK will go back to evening EMH.
