HLTHAGE 3N03: Aging and Mental Health
Department of Health, Aging and Society
McMaster University
WINTER 2024
Test #1 (20%): February 13th, 2024

Full name: Lana El Barghouthi

Student Number: 400333441

Please read instructions:

 Place your name and student number in the space provided above.
 For Part A (multiple choice and true/false), please use the highlight feature in Word to
indicate your answer (if you do not have this feature, it is your responsibility to choose a
way that makes your answer clear)
 For parts C and D, please pay attention to the mark total for each question and do not
“over answer” (i.e., providing irrelevant information).
 Please save the file as a Word doc: full name_Test 1 [mine would be: Aly Bailey_Test 1].
Please note tests that are submitted as an unreadable file and need to be resubmitted
will be considered late.
o Submitting a PDF file is another option but is not preferred.
 You will submit your Word file to the assignment tool named “Test 1” under
“Assessments->Assignments” by Wednesday February 14th 7:00PM (ET)
 You can use your class notes and the materials I have posted on Avenue to Learn (it is
“open book”). I discourage using materials outside of the course (e.g., Googling your
answer), since the test is designed to assess course material only and because that
would be considered academic dishonesty.
 It is expected you work independently on your test. Academic integrity (e.g., plagiarism)
will be assessed.
 I will do my best to respond to emails during the 24-hour period.

Late Policy
The Late Policy in the course outline for late tests is 10% per day (beginning at 7:01PM). By
remaining enrolled in the course, you consent to these policies.
