Grouping Users!

Good Day,

I’m looking for an urgent help! I am a teacher and I need to put my students in groups depending on their levels! What I exactly need is ‘categories classification’. In other words, I want every level (group) of my students see certain categories that I define earlier. Could you please help me find any appropriate plugin!

I’ve tried many plugins: ‘user access manager’, ‘user assign categories’, ‘restrict categories’, and ‘Simply exclude’. None of them fit my purpose!

I welcome any help…

Best,
