Professional Certified Operator’s E-Bulletin
Volume 1, No. 3, December 2, 1999 As a new feature of the E-Bulletin, AceOps will periodically email test questions to you. Just email, fax, send, or call us with your answers, and we'll correct them and let you know how you did. This first issue focuses on math. Future issues will include math and practice certification exam questions. We hope you'll like this feature and find it helpful. Please let us know how we make it even better. Feel free to submit questions to share with the group! Also, we would appreciate any operator or plant email addresses that you can share with us so that we can send this to as many operators as possible. Please pass it on! Thanks!!!
