Sources for exploring majors and scheduling classes:

The General Catalogue is available on line, and it includes the information that you will need to do research for the exploration of majors assignment, including the requirements for various majors.  The Catalogue homepage also includes links to the spring course schedule and to the on-line course catalogue, which provides brief descriptions of courses for you to cross check courses that you are interested in.

Instructors' student evaluations are available on line.  Many instructors' classes are not included, through no fault of their own.  For example, I have taught a workshop for all the teachers in composition, and that training program does not use the standard course evaluation.

You also have a wide array of learning resources at your finger tips:  

The First-Year Center provides advising, opportunities to explore majors, and other support programs.
The University of Arizona Writing Center provides peer tutoring and links to on-line writing centers.
On-line readings on learning strategies provide you with advice on how to read more efficiently, take better notes, and plan your schedule more effectively.
Research Instruction Online covers how to find books, articles and internet sources.
RIO also includes advice on researching and writing papers.
RIO will help you get oriented to the world-wide web. 
Other sites on the web can help you analyze sources.
