Onto the second semester...

So what did you think of the midterm? I know it was tough; this is a pretty authentic AP experience. Now that you have an idea about the level of difficulty, you have a better idea of how to prepare yourself for the AP exam!

I'm looking forward to our next semester...believe it or not, we only have one more full quarter before the AP exam! We will spend about 3 weeks finishing our "methods of data collection" unit, and then we'll start learning about my favorite stuff, hypothesis tests and confidence intervals!

On Tuesday night you will have the reading questions below for homework. Feel free to get them done (so you don't have any homework on Tuesday night)!
