I just made a joke(enter also means going inside)
In my country we also have such(matura, abitur)

Sorry, maybe I didn't explain myself.
I'm from Spain, here almost all universities are "public", that means you pay a little, but you need really good grades in highschool (that counts a 60%), and to do a hard exam of each subject done by the government called "Selectivo" (selective exam, that counts a 40%), and depending on your mark you can do certain degrees or not, but you always have to pass it.
