Hi Lukas,
Yes, given the number of attending students (expected 40+), we will offer exercises in both slots (Wed and Thu).
Indeed, only 4 exercise sessions will take place -- the rest of the "exercise" time budget is covered by the projects and their advising/supervision.
In the week when Thu is a holiday (May 18), we might have the exercise only in the Wed slot, but we may also offer an additional slot -- we'll inform you in time.
Cheers,
Goran
