Unit 2 Pretest
Directions: We haven’t yet studied any concepts from Unit 2, however, you may already
know some of them from previous years and then you will be bored during those lessons.
Complete the problems as best as you can. If you don’t know how to solve something
skip it and leave it blank. As we learn you can look back at this pretest and make
corrections showing what you’ve learned. After we finish Unit 2 you will know how to
do all of these concepts!
