Preparing & Format
• Re-read the text and handouts
• Study the homework assignments
• Redo the quizzes
• Try exercises in text
• Get a good night’s sleep
• Possibly different kinds of questions
– Mostly problem solving—similar to quizzes, perhaps bigger
– Short answer
– Maybe a few T / F, M / C, single answer questions

Final Grades
• 5% participation, 30% quizzes, 20% homeworks, 10% in-
class exercises, 35% final
– Lowest three quiz grades dropped
• Unbiased grading – compute and sort:
• >= 98 : A+
– Probably only one A+ per class
• > 93 : A
• > 90 : A• > 86 : B+
• > 80 : B
• > 75 : B• > 65 : C
• I will “slide the line” down to an appropriate “break
point”

What I Want You to Take Away
You in 5 years
Forgot everything about testing and high
quality software
Me
Remember testing, but develop software
the “same old way”
Use these concepts to hand-design more
effective tests for your software
Apply automation and criteria when
possible
Convince your company to develop a
quality mindset
