At the following links you can find the following examples of practice
tests for the entrance examination at the Faculty of Mechanical
Engineering, University of Belgrade. The tests are not a perfect
simulation of the actual entrance examination, but they can certainly
serve as a very useful way to check your knowledge.
The number of assignments, as well as the scoring method, is the same
as in the entrance examination. The structure of the assignments is
also the same: one third of the problems in each test is easy, one
third is of medium difficulty, and the final third belongs to the
category of more difficult.
