Not all Course Prefixes (the letters that precede the course number) are obvious. (UCO - "First Year Seminar" - as an example) Check the list of course prefixes so you can find the correct course.
Be sure to pay very careful attention to both the prefix and the course number. ENG 2050 is not the same as ENG 2010.
*Make a note of building abbreviations when planning your schedule. Use the interactive campus map to see where buildings are located. You can get to most classes in 10-15 minutes.
