Hi Arran, By referring to the updated spec for the project. I still see the following description. In question 8 : " implement the three test cases you described in question 6" As per my understanding, it should be something like: "Implement the three test cases you described in question 7", For question 7 we are creating 3 test cases not for question 6. In question 7 : " so you can refer to it in question 7" As per my understanding, it should be something like: "So you can refer to it in question 8" Please let me know if my understanding is wrong something else is expected and I am missing here. Thanks.
