I hereby certify that I am taking this assessment with only the material (that is, my power point slide show that has only images and no words on it) that the professor has specifically allowed me to use. The username and password that I use to log in are mine and act as my signature.By choosing TRUE below I am also acknowledging that the following work is my own. I also acknowledge that if I am found to have cheated or used any assistance not specifically allowed by the professor, Alvin Community College as well as the professor have the right to assign a zero on this assessment and even remove me from the course while taking further appropriate punitive measures.Accept the statement by choosing TRUE below. If you do not choose TRUE, then this assessment will earn an automatic zero for a grade, and you may not be allowed to re-take it.
