Instructions

It's been a pleasure being your teacher this school year--I'm 
SO proud of your achievements! 
Keep in mind that this test is a snapshot of what you've learned. That said, make sure to read each question carefully and choose the best answer(s). It's preferable to avoid writing on the copy you receive--this will allow another student to use it as well. Nevertheless, if you'd like to annotate, please GO for it. You GOT this!
