I hope everyone else don-t mind my use of this topic for explanation..
The thing is that by the old system in 4 years you could repeat only 2 years, doesn-t matter which year.. the thing with first year is that if you don-t pass, you can repeat (now I have no other option since the system change and the aplications for other studies are closed ) and if you fail the second time you can not repeat anymore.. you can repeat a year only once..so if in case I fail next year too, or if I wish to go study smth else I have to sign in first year again and that can not be for free anymore since I already used my two free years.. so the Uni charges you for signing in a not regular studies, and than if you pass it you can transfer into regular studies and for free..( I dunno the english word of exceptional studying) so in this case you get to pay only one year.. This works for any Uni in any place in my country..
The studying process and exams are the same just with the difference that you are for the third time in first year and you have to pay for it.
Have a nice meeting and the rest of the day!
