I'm at a 141 school that uses test prep software for the ground school mid-term and the ground school final. I cannot stand it. I (and other instructors) feel that the students simply memorize the prep material and skip the finer parts taught in ground. This later becomes apparent during orals later on down the road. It appears that many students simply memorize the book and don't try to understand the material. I believe that we can bring our testing in house and get away from using published test prep materials all together. Am I missing something? Am I just old skool? I understand that there is gouge out there and that memorization has its place in aviation however, when the answers are memorized with no sense of understanding, I get a little concerned.
