The offer of consultation DNB and MLS will change to open consultation hours as of July. Mind the information on the webpage of Office of Studies including the periods of absence during summer.
Office hours are cancelled when out of office.
The change was made because students often did not turn up for the booked appointments (or cancelled shortly beforehand), which led to frustration and more planning effort on all sides. Hoping, that open consultation hours will support your studies with more flexibility.
