I just finished ED104, and found it informative. However, on a completely different subject, my students took their EPA certification test yesterday. This morning was a terrible let-down, when I saw the results. I have the standard study packet, video, and sample questions. I covered all the material daily for five days prior to the test. Still the results were horrible. I tell all my students, we teach the information they will need to figure out any problem they may encounter in the field. It's all a matter of applying what they know to the situation at hand. With these certification tests that doesn't work. It's so frustrating, to have to teach them to memorize dates from 15 to 20 years ago. And worse yet, how to be good test answer- guessers.
