My mother is visiting my university

My mother told me she plans on visiting my uni in person to get information on my results, attendance ect. From my understanding she wouldn't be allowed even if she does go in person but I'm still anxious because she says she has 'special circumstances' which allow her to find things out. I don't know what these would be and it's very possible she's making them up just to scare me but could anyone shed some light on the rules? She's very controlling and I'm worried she'll convince them somehow
