About Your Shopping Cart
Registering for classes is a lot like shopping online. Once you've logged in to CU Boulder Class Search, search for classes and select "Add to Cart" to set aside the ones you want to take.
Those classes will remain in your cart until you finish enrolling or remove them—however, they aren't yours yet. If other students register before you do, it's possible one or more classes in your cart will be closed by the time you register. If that happens, don't panic. Consider joining the class waitlist or registering for a different section of the same class.
