Some time ago Berkeley switched from Telebears to a new registration system developed by PeopleSoft/Oracle. Needless to say, it's garbage. I wrote a couple scripts to pull class data from the API in an effort to help me get into our heavily oversubscribed CS courses by searching for open sections, but the system seems to be designed to make using it as painful and worthless as possible. Luckily this semester the EECS department has put dummy sections in for all classes so students who are able to register for a lecture don't get permanently stuck on the waiting list because of a full section.

College administrators who are considering Oracle for your registration needs, please consider anyone else instead, for everyone's sake.
