Polls for new lecture/exercise times

As discussed in the lecture, there are basically two options to deal with the Tuesday slots in this course: i) move the exercises or ii) go for a compact lecture setup on Tuesdays, with a common lunch break for everyone who wants to join. Note that ii) would preliminarily only be for a few weeks, then we'd evaluate how this works. Please take the poll here. 

If the exercise sessions need to be moved, please indicate your availability here. NB: you must fill this in, independently of your preferences in the poll above!
