What are my chances???

<p>I just completed my first semester of my Junior year at St. John's University. I just got my first non (A,A-) i received a C+ and a B+. In HS on my SATs(640 Math, 530 Reading). I was wondering if it is still possible to transfer and if so what are my chances of getting into a top 20 program, possibly in business. Secondly, would it even be worth it to transfer now? I cant stand being in this environment any longer and need to get away from St. John's.</p>
