Life Science This is review for the GA Milestones test. On a piece of notebook paper, head your paper with your name, homeroom and Life Science. Number your paper - 1-45. You only need to write the letter of the correct answer on your paper. You are welcome to use your ISN or your book to answer the questions. You may work with a partner if you pick your partner wisely. Good luck and turn it in to the science basket when you are done.
