Help .. Route mix php laravel

Something strange happens. It happens that I have three groups of routes one for the admin and the other for secretary and teacher, what happens is that I put the controllers in each one, so that the admin can also see it, but at the time that shows the views, ejm I am in admin mode, in the student view and edit, I get the secretary url. Something that mixes and I do not know how I can solve it.
