Separating User Panel from Admin Panel

How do i separate usercontroller and admin controller.

User goes to Quiz panel.

Admin goes to Admin panel

Also in admin panel, i need CRUD for users in admin panel

Route::get('/', function () {
    return view('quiz');
});

Route::group(['as' => 'admin::','middleware' => 'auth'], function () {
    Route::get('dashboard', ['as' => 'dashboard', function () {
        return view('pages.index');
    }]);
    Route::resource('admin', 'adminController');
    Route::resource('user', 'userController');
});
