As soon as I got comfortable with not reading the question stem in these lessons.... Damn. I promise I read them almost all of the time up until I mistakenly started to realize it's wasting time and it's probably going to be the topic of the lesson. This was good to learn not to do this early on.

Wait what are people talking about "hard" and "medium" modes? I got a 5/5 but I don't know if it was medium or hard or how to take the other.

I just want to say that I'm extremely proud of myself for getting this right in the blind review. I got it wrong the first time, but it comforts me that it was simply the time pressure.
