__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.
