When it comes to reapplying, you definitely want to show that you've improved upon yourself.
When i was a senior in college, i got into dental school in mississippi and decided to decline the acceptance and move to texas to become a resident. After applying the next year as a non resident, this cycle i was a resident. I took a kaplan prep class and increased my aa from a 19 to a 20 and pat from 18 to 21 as well as all my individual sections pretty significantly with organic going from a 19 to 21, reading to 23, etc. I worked as a treatment coordinator at a dental office for 6 months and began getting my masters in Biomedical sciences. I maintained a 3.7 in my first semester, which A&M really liked since the program was all essentially classes we'll be taking in D1. I continued to volunteer with organizations i care about. Most importantly, i expressed how much i had improved upon my past application in my essays. You want them to be somewhat different than past essays. You need to show that you care enough about getting into school that you are willing to continue learning about the industry and science in general! It worked for me and i got in this year. No connections, no one helping me behind the scences, just hard work and trying to show that i really want this.
Hope that helps some!
