Although, it will take years before we can offer all, or even most, of our courses on-line, we would like to know what courses you would be interested in taking on-line. This knowledge will help use plan our future development work. Descriptions of all our courses are shown in the BS curriculum. Many of the courses have pre-requisites that must be satisfied by the student before taking the course. This is to ensure that the student has the proper background to be able to understand the material in the course. Thus to take SUR 455-Precise Positioning Systems, you must take SUR 241, 341, 351, and 441. Please consider this when you make your selections.
