Applying for transfer to A&M spring 2018. I have a couple questions

Hi, I applied to the liberal arts school at Texas A&M for spring 2018. My first choice major is psychology, and my second choice major is communications. My current GPA is a 3.3 (an A B average) and I have 28 hours. My questions are, is a 3.3 a competitive enough GPA? Should I try and add some letters of recommendation, or are they not that big of a deal?Also, does anyone know how long it will take to hear back? Thanks!
