RULES FOR 481 ASSESSMENT QUIZ :
Here is information regarding the upcoming EEE481 Assessment Quiz.
The quiz should be taken during regular lab sessions, in the lab.
Please let the TA (ashfaque@asu.edu) and myself know (via email) when you will be taking the quiz.

The quiz is Closed books, closed notes
No calculators, no computers, no communication devices
Open minds
NOTE:
Studying for your assessment quiz will significantly help you with the course material. Come see me if you need suitable references to study from.
