I would totally disagree with you on this. A good or bad DAT score has no indication of whether you are a good or bad student. It is the long term education received that matters. Answering 40 questions in biology does not show that you know entire biology. Just because you did well on plant biology or ecology or classification of Animal kingdom or PAT or QR or English does not mean you will not do well in dental school. They have nothing even close to medical subjects. Maybe someone was super nervous or was not well or did not study one particular section well and was bombed with that in the test. Sometimes it is luck too, one might get a harder section than the other. So how do you compare students on one test when they were not even tested on the same level and material. In fact I feel that DAT is a bad way to measure a students ability. If one was really on the admissions then he would already know if he gets students with all 4.0s or low GPAs from that University. I come from a University that is very hard to grade and I know how it feels when you don't get the grades that you need. To give you an estimate, in my University only 25 students out of 400 students got an A in gen chem and it was worse in orgo. So it would be wrong to blame the University. This is the reason why, correctly, admissions looks not only at the DAT but the student as overall, in all fields and aspects.
