PRACTICE FINAL
Attempt everything on this because it is a good example of what your final will look like! I would
build my notecard after trying to accomplish this practice final. The answers will be on my class
page later today or early tomorrow. I will collect this either today (if you aren’t doing good
work) or on the day of the final!!! Remember to email me with questions or show up to
the lunch period for help!
