I think you need to evaluate and identify your weak areas. I do not agree that more schools applied to are better. You applied to plenty, but of course, knowing their interview timelines are important. But, from reading this all the way down, you go from a 4.0 and 19 dat, to a 3.7 and some 17-18's. And I would be willing to bet your calculated gpa is even lower, because it usually is after the AADSAS gpa calculation. Mine was. So, being realistic, you now are comparable to every other applicant, and I am not surprised that you haven't heard back as you applied later. This is not to make you alarmed or frustrated! Realistically, your scores are good! Your gpa is good! But make sure you aren't exaggerating to yourself. My highest dat score was a 23. My lowest was a 16. I was accepted to only one school so far, and that was only this week. I applied in July. If you have to reapply, my advice would be that 17's arent too highly favored, as I know, so try to increase that and apply earlier. But you dont need to apply to 10+ schools. That is terribly expensive, plus you'll spend more flying out to interviews! Good luck.
