IMPORTANT: This exam is divided into 9 parts and labeled A to I. Each section contains questions of similar achievement level. Complete the 1st and 2nd section of each of the three overall expectations (Part A & B - Trigonometry, Part D & E - Analytic Geometry and Part G & H -Quadratics). At the end of the exam if time permits, complete the three remaining sections (Part C, F and I). Answer each question to the best of your ability, that may include explaining what you are doing and why.

In the interest of saving paper, this exam does not provide space for graphs and solutions. Please answer your questions on a separate sheet of paper and label each question carefully. Your actual board-wide exam on Wednesday June 17, 2010 @ 8:45 a.m. will provide space for your solutions.

This practice exam is way longer than the actual exam. You will have more than enough time to complete the real exam. This will probably take between 8 and 10 hours to complete.
