For those of you signing up for classes for the fall semester, use the link below as a guide. You want to make completing these courses your goal if you are applying after two years. If you are applying after one year, it is best to have half of them completed. By that I mean, you should dabble in all subject areas. It is not advisable to take (for instance) all humanities or all social science courses in one semester. Think of your semester as a platter filled with many different samples of coursework.
