What are the steps in order to change your classes today? ie, Log on to SOLAR then press Course selection for the SEP 2012 Session??

Yes. It's exactly what you did when you chose your courses back in June, except this time, there'll be more options. Remember when you had to select the course, the term, and whether you wanted the day or evening class? Well now you'll have the option of also choosing which core/tutorial/lab number you want.
