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.

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.
