Unfortunately this is not a joke, since the next academic year (2017/2018) there will be a relevant increase in the taxes.
Specifically, the update doesn't deal with all the students. The changes are:
1) The first instalment which amounted to € 883,58 for the bachelor and € 845,58 for the master will be of the same amount for everybody € 883,58.
2) Taxes for the 9th and 10th bands will increase of nearly € 100 for students in the 9th band and € 250 for students in the 10th.
