Grade 12 Diploma Examination
Description
Time:
This examination was developed to be completed in 2.5 h; however, you may take an additional 0.5 h to complete the examination. This is a closed-book
examination consisting of • 37 multiple-choice and 12 numerical-
response questions, of equal value, worth 70% of the examination • 2 written-response questions, of equal value, worth a total of 30% of the examination This examination contains sets of related questions. A set of questions may contain multiple-choice and/or numerical-response questions. A tear-out Physics Data Sheet is included near the back of this booklet. A Periodic Table of the Elements is also provided. Note: The perforated pages at the back of this booklet may be torn out and used for your rough work. No marks
will be given for work done on the tear-out pages. Instructions
• You are expected to provide your own calculator. You may use any scientific calculator or a graphing calculator approved by Alberta Learning. • You are expected to have cleared your calculator of all information that is stored in the programmable or parametric memory. • Fill in the information required on the answer sheet and the examination booklet as directed by the presiding examiner. • Read each question carefully. • Consider all numbers used in the examination to be the result of a measurement or observation. • When performing calculations, use the values of constants provided on the tear-out sheet. Do not
use the values programmed in your calculator. • If you wish to change an answer, erase all
traces of your first answer. • Do not fold the answer sheet. • The presiding examiner will collect your answer sheet and examination booklet and send them to Alberta Learning. • Now turn this page and read the detailed instructions for answering machine-scored and written-response questions. NEW NEW
ii Multiple Choice
• Decide which of the choices best
completes the statement or answers the question. • Locate that question number on the separate answer sheet provided and fill in the circle that corresponds to your choice. Example This examination is for the subject of A.
