I changed an accelerated Math class from a semester course to a year long course. I had some kids loaded in some of the classes but when I changed it and ran load it kicked all the students out of the classes. It didn't load any of them. Any ideas why?
Yes, most classes run all semester (there are some exceptions at certain schools, where there are shorter classes for fewer credits that might only go half a semester). Sometime in October, most likely, you will meet with your academic advisor and start the process of registering for spring semester. In most cases a first year student will have an entirely different set of classes in the spring, though there are sequences that may continue (i.e. Biology 101 becomes Biology 111).
