Redmine

Hi ,

I have a requirement in which I want to have different classes ( we can map it to projects ).
Classes can have multiple students ( users ) and teacher ( project owner ) can give assignments to
various users ( like creating a subproject ).

Now student can start with assignment completion ,which may be spread over various stages ( we can call them tickets).

Can you think that can be realised with redmine...

Any pointers to specfic plugins to use..

Thanks a lot
