School iPad restrictions

Hi, I have a school iPad with restrictions on them when I’m at school. I am not trying to get rid of the restrictions completely but for the last week or two I can’t go on my home apps completely. This usually happens at school but after school I can go on my at home apps yet now whenever I try open an app I use at home in the App Store it says my restrictions are still on. I asked other people who have an iPad from that school and they said that their restrictions turn off when they go home so it must be a problem with my iPad. If you could help me I’d be really grateful, thank you.
