Homework Assignments
 15 points
 You will NOT have to do a circuit diagram or truth table.
 Do each assignment and understand what you did.
 Remember something about the assignment details. For
example, “I imported a plain text file into Google Docs.”
 Remember what tools you used for what task.
 You will not have to know the details of what key or menu item
to use for a specific task.
 Do each assignment and understand what you did.
 Remember something about the assignment details. For
example, “I had to figure out the mileage by car and by foot to
my elementary school.”
 Remember what tools you used for what task.

How to Study
 Look at old exams.
 Do the lab assignments (especially the
Spreadsheet assignment).
 Know the vocabulary and acronyms, what
they stand for and what they mean.
 SLEEP!!!
What to bring
 Pencils and erasers
 We will provide scratch paper
 You can use a calculator, but leave the cell
phones in the bag!
Hint: Take the exam backwards. Many times
questions from the back of an exam will help
with questions at the beginning.
