Frank and Jim, That was precisely what I needed. Thanks for taking the time to help me out. I am currently leaning in the following direction: 1. Eliminate the online reading quiz. 2. Start most classes with an iRAT, followed by a tRAT. Since my class begins at 9:00 am Saturday morning, tardiness is an ongoing problem. I often begin assignments soon after 9:00 am, but if I were to have weekly iRATs, students would know that lateness could have a significant impact on their grades. Thanks again, Mike
