I totally agree as well. I, too, have a high GPA & I thought I understood everything. I took the practice test on this site as well as the 4 tests on E&Z site (i.e. Multiple Choice & true/false) & did very well. Study group would be great, or at the least one study session before a test. Just email me by clicking on my email above. I'm glad I'm not the only one that feels I didn't do well considering I thought I underdstood the main points of the chapters. Thanks, Vee
