If you are a Freshman, Sophomore, or Transfer student your General College advisor is responsible for registering you in your classes. Once you leave General College (after Sophomore year), you are expected to meet with an advisor in your specific area. If you are a Junior or Senior, you will be given your PIN by your major specific advisor once you review your go.abadiadetortoreos.com account together. Once you have your PIN and discuss the classes with your advisor, you will login to Banner Online Services using your A number and password. Click on the Student Services and Financial Aid tab, click Course Enrollment and Registration tab, click the Add/Drop classes tab, choose the semester, and then look for the classes discussed with your major advisor.
