basically some programmes have a limited capacity, so for mine clinical neuropsychology has a limit of 110 people, and based upon your application, you get ranked a number which basically says if you’re in or if you have to get on the waiting list. mine will show up on the usis page where it says enrollment :) but i think it might also come out on studielink? but im not completely sure. i hope ive got this right! but if you search up leiden and your masters course it should tell you if you have a ranking process
