Restricting category and menu access to role

Hello Guys,

I’ve tried about 4 plugins that claim to restrict access by role in wordpress, but I’m racking my brains and could do with pointing in the right direction of where to start.

I’m building a site that has several categories of post (these categories are actually modules of a course). I’m trying to restrict access to these categories so I can let course students gain access as they progress through the course, but just can’t seem to find a plugin that will allow me to restrict category (and menu ideally) access in this way. In Drupal it’s reasonably easy, but in wordpress I haven’t a clue where to start…

…could some kind soul help? I’m happy to donate the a beer or two for someone’s time to help me out!

Best regards,
