Classes start this week.  But keep taking registrations.  Two reasons:

1.The first Unit of each course won't end until Sunday, so your students won't miss a thing if they register this week.  Keep sending us your registrations.  

2.If someone wants to register for a UGotClass CERTIFICATE, keep taking the registrations through next week, Friday February 17.  Most people are more than happy to make up the first week in order to complete the Certificate by April.  Otherwise, they have to wait another two months to start.
