If you say fail the exam to enter a medical university you can try next year(or in a different city) but yeah if you prefer filtering by money rather then knowledge then what I can say is a very american way so I am not surprised.

Here in Romania they made a mixed system, there are say 50 free sports and 50+ paid spots so if you have the money you can have an advantage over the poor people (hopefully there are no many competitors rich and smarter then you)
