Jane, great post and glad to see your students have a resource they can go to when they have concerns about testing. For many institutions, too many in fact, they only see the side of student testing that assumes students are not studying properly and this is the only factor they see when test scores are not good. Some students just do not know how to prepare and take a test. Sounds funny but they may have some from a school system that did not take the time to prepare them for college or they have been away from college for so long they have forgotten best practices on how to prepare and how to actually take a test. The more time you can spend with them as an instructor the better results you will receive.
