How Do I Write Exams
• 40%
– Problems similar to
examples in the book or
class lectures
• 30%

How to Study
• Memorization
– Will get you to 40%
– But there is lots of material that
must be learned to build the
foundation of understanding
• Understanding
– The other 60%
– Most questions on a test will be
unfamiliar to you. You must apply
your knowledge of facts and your
understanding of concepts.
– Take a first step and move
forward
• Practice
– The only path to
understanding

the instructor must
be…
– Neat and readable
– In pen or computer
output
– Your 2nd or 3rd draft
– The type of document
you would hand your
boss.
• Don’t go overboard
