I do not understand your confusion. The test appears to be functioning as expected. What do you mean by the iterator being "at the last element"? `NoSuchElementException` should only be thrown when there is no element to return. The test you appear to be referring to constructs a `MockStudentList` containing 4 students, and then consumes exactly 4 elements from the `StudentListIterator`. At no point should the iterator run out of elements. Gozz
