This thread belongs in off-topic.

I see this is your first post, I don't want to be rude but there are better forums (and yahoo answers) for these off-the-wall questions. This is a Linux forum, a Maemo Linux forum.

As far as your question goes. Yes, yes it is possible to get a registration ticket for Spring. However it will depend on the college if they will allow this, you may need to go in-person to register, however you can in most cases do this online. A special note, in some cases if you register for a term and do not register for a class, then you will be in registration limbo and have to to wait a full year before you can register due to bugs in their systems.
