You can register for a closed class, but it will prompt you to add youself to the WaitList. Make sure that you have activated your LakeHawk Mail account. When a registered student drops from the class, the next person on the waitlist will be notified via their LakeHawk Mail. That student will have 24 hours to accept or reject the seat before the Waitlist spot is emailed to the next person. (Refer to WaitList FAQ on myLSSC)
