I had a sub 3.0 cGPA my first semester and ended up getting into schools. If you're at a 3.3 cGPA now, you must have worked hard to bring your grades up the last two years, so that's a positive for schools reviewing your application. You can talk about your upward trend at interviews (if you get some) and what spurred you to take school more seriously as well.
A 3.3 cGPA won't hold you back that much provided the rest of your application is above average (DAT scores, volunteering, work, possible research, etc.)
