I'm an Animal Science major and pretty much agree with all of this. I wasn't pre-dent to start out with (officially decided like a few months before I applied) and was really frustrated when I realized I wanted to be a dentist and felt like my major was a waste. It ended up being a huge help, and I would not change a thing. A&M is a good school with generally challenging sciences, so you will get out of your classes what you put in. If you work hard and make mostly As in your general science classes, you should do well on the DAT. Most of the animal science classes are easier than core sciences, but a lot of this is due to smaller classes with professors that are extremely personable. This can also lead to more access to research positions, etc. They are flexible with your degree plan, so if you want to take something more relevant to dental school like Histology for example, you can sometimes sub in classes for degree requirements. I don't know that I would recommend choosing it just to stand out, though. I had an ag background so it made sense for me to choose ANSC over BIMS, but some people that had never been around livestock before hated a lot of the hands-on classes. If I had known I would eventually apply to dental school, I have no idea what I would've chosen... I also was just accepted so my views may have been different if I hadn't gotten in. Hope this helps y'all!
