Changing my last name in college???

I start college next semester as a transfer student and I would like to change the last name associated with my file. Legally I have both of my parents last name but my previous school records only has my mom's last name. When I applied for the college I'm going to attend I used both of my parents last names since that's my legal name. Do you think I will be able to change it to just my mom's so that everything matches up, as well as making it easier to match my transfer papers up. Will this mess up my college information and will I have to wait till the semester starts? I would like to duo this veggie I have to register fire classes. Thanks!
