From what I have gathered from the relevant university sites, there seem to be no real discernible differences between the actual content studied in the courses; they are all first semester so they all more or less cover the same basic introductory content. However, there are differences in tuition costs and mandatory intensive courses. I hope to find out some more information regarding the math courses this week so I will let you know if anything else comes to light. May I ask which subject you have accelerated in? Math?
