(I'm doing it in 12)

Note that the test does not consume the iterator until exhaustion. It only consumes the first six elements. To quote the project specification: "The iterator should not simply load the entire list and then iterate over it, as if we need to access only a prefix or suffix of the list, this would be extremely inefficient."

The specification also says "You are advised to read the documentation comments for the interfaces in [the studentapi] package carefully." This documentation has the information you need.
