There isn't one typical schedule or one standard for students interested in a particular major. Because the first two years emphasize general requirements, a wide variety of course selections will be both appropriate and desirable.
As you plan your schedule, think of alternates as well as your preferred four courses. Your four academic (credit) courses ideally should represent four different subjects. The first semester is not the time to double up in your possible major. It is a time to open yourself to new subjects, to continue a foreign language you have begun or to start a new language. Many students will take a writing course in the fall while others may choose to wait until spring. Taking a diverse group of courses in your first year has another huge advantage: you open yourself to new interests that you didn't know you had.
All students must register for and take four credit courses and will also be registered automatically for the non-credit "Davidson 101" course. That non-credit course is not one of the four, and you do not include it in your registration selections. Other non-credit courses (applied music not for credit; military science; physical education) likewise do not count as one of your four courses, and you will not be able to include them in registering your course preferences through the WebTree process.
Having pre-college credits (AP, etc) does not allow a student to register for fewer than four courses in the fall. If the initial process of registration does not leave you with four courses, you will complete and fine-tune your schedule during orientation, at which time you will have the opportunity to work with your faculty adviser.
