Assignments
1) Please complete the Virginia State Algebra Exam. This is a VERY large file there are 50 problems and only one problem per page. I suggest using your computer to download this file and work your problems out on a separate sheet of paper. There is one concept we did not cover: standard deviation. Just do the best you can on those - I will not be counting those problems. Please record your answers on the answer sheet and submit it to me by no later than noon on Monday, May 29th. Good luck and thanks for a great year!
