It should have slice first parameter as $index & then second one would be 1

$scope.formData.university.splice($index, 1);

Note: using $index for deleting element would be risky if you are applying filtering on ng-repeat

Instead of that you could add some unique prop in your each element of ng-repeat you could add id in it, so that while deleting you could pass that id and then do find index of that element and delete that element from an array like the same way I did wrote above code.
