There will be 24 questions on the Exam.  Each question is worth 1-3 points; most are 2 points.  The questions will be divided into 3 pages. Each page will have 6-10 questions.  You WILL be able to go back and forth between the pages as much as you want.  Anne will provide a periodic table (from the Course Workbook) and pH color guide and on each page.  You are NOT allowed to use a phone or a graphing calculator on the exam. If you print out the periodic table that Anne provides (in Content > Study and also in the Printed Project), it must NOT have anything written on it AND you must hold it up (front & back) during the room scan, along with any blank paper for working out calculations.  Which statement is CORRECT?
