how to access parents scope from ng-click

I need to pass the value of $scope.correct into the checkAnswer function but it keeps coming up undefined. ng-click only seems to understand it's own scope. What am I doing wrong?

angular.module('Tutorials', ['functions']).controller('getAnswers', function ($scope, $element){
    $scope.verbs = conjugate(conjugationsets[tutorial_number][questionnum]);
    $scope.correct = $scope.verbs.conjugations[0].text; 
    $scope.randomizeAnswers = function () {

      fisherYates($scope.verbs.conjugations);
    }();

    $scope.checkAnswer = function (answer, correct){
        checkanswer($scope, answer, correct);
    }
});
