Classes fill up quickly and although advisors will probably be able to find what you need, you will have the best range of choices if you meet with an advisor early!
Check the catalog and class schedule BEFORE you come to see an advisor. You do not need to make all your decisions but it helps to have some idea of the general area / classes you are interested in taking. It also helps if you have some idea of your commitments outside school (work, family, etc.) so we can tailor a schedule to meet your needs.
The later in the registration period you come, the longer you are likely to wait. PLEASE BE PATIENT and use the waiting time to check the semester Schedule, and make sure you have the necessary paperwork completed (admission to the college, educational transcripts, and placement test results).
