The final for Discovering Computers needs to be finished before the end
of the course. Although you may take it anytime before the end of next
week, you may want to finish a few days early since many times a
student will try to take the exam and have technical difficulties or
not get around to it until after the last day of class. By giving an
early target, it eliminates shutting such people out and giving them an
F or a D after they have performed well in all other respects.
The
final for Discovering Computers covers Chapters 8-15
and consists of 150 multiple
choice and true/false type questions on terminology mostly taken
from the book. For any questions that are not in the book, you may use the internet to find answers.
The exam is timed - you have 3 hours to finish.
