This time I wanted to combine some of the confusions and unknown information from the pre-test with the new things I learned from the lesson. The biggest topic that came up throughout the test was significant numbers. I was thinking that I could have a pretty good guess at what they were, but once I got to learning what they actually were in the lesson, I found out I was way off. There are many rules to these significant figures making it hard enough, but then you have got to deal with addition and subtraction. That adds a whole new level of confusion to this lesson. Overall, I think I am getting the hang of it pretty well, and I feel pretty good about the quiz on Monday.

My thoughts were very similar to yours about the pre test and the lessons. When I took the pre test, I thought I had it all in the bag but apparently not. Because the lessons that we learned just confused me further. Its just a jumbled mess of numbers in my head.
