Suggestions: 1) Complain strongly to your department chair. If he/she fails to satisfy you make an appointment to talk to the A&S Dean. These officials don't want upset students. 2) Talk to the undergrad advisor. As several in this thread have pointed out, the enrollment limits on some of your courses may not be set in concrete. 3) Talk to the professor. Some of them may be willing to let you take the course as a 'Topics' course. It will probably mean attending the same class meeting and taking the same exams, but it will allow the prof to get some credit for having an extra student. 4) Be ready to drop-and-add. Opportunities to enroll nearly always arise. 5) Don't be upset. Just be adamant about getting it right. 6) If worse comes to worse, remember that an extra year or two at university can be fun! God bless Texas!
