First time posting. I think I have found a potential error in Q.2 of the Referring to the current instance test, I say potential because I am fairly new at coding and could be looking at it wrong. Anyway, the answer to [Q.2] (https://www.hackingwithswift.com/review/referring-to-the-current-instance) is true, but I believe it should be false because the second parameter of the initializer is superPowers not powers so .self is not needed when referring to the property powers. Other questions in the test do this same thing and thier answer is false. If I am wrong please explain to me how, I've taken the test 3 times now because of that one question, trying to figure out what I am missing. Thank you.

self is not needed there, but it isn't an error to include it. The code is valid Swift.

I understand now. I retook the test and read the answers for the other questions that I had mentioned and realized that I hadn't read them carefully enough. Thank you for the help.
