Class registration dates and deadlines differ depending on your student status (currently enrolled, previously enrolled, new students, non-degree, etc.).
For in-person registration, forms may be picked up at your advisor's office or at One Stop Student Services. For online registration, log into BlazerNET, click on the "Registration" link in the green ribbon, then from the Registration menu click the "Add, Drop, or Withdraw from Classes" link.
