the CMS seems to have problems with the number of tutorial slots that we have opened - I'm not sure if you can only select from four of them, but in any case we can only see your selection for four of them.
So let's do this by hand: can you please include in your submission of the discussion slot groups also two lines
with the times that you are available?
The possible time slots are Fridays and Mondays from 9 to 11, every 20 minutes.
Sorry for the inconvenience, see you tomorrow!
