Dear Irina,
Of course it is possible to apply for a master program if you got your bachelor degree in 2009. The fact that there is maximum number of waiting semesters does not mean that you cannot apply anymore after you have reached that number. 10 semesters is just the maximum number of waiting semesters which are considered for being admitted on the basis of the waiting period between the first degree and the application for the master program. Further information on admission for a master program based on waiting time is provided here:
