As I've been looking at universities this year, a lot of them offer a joint bachelors and masters in math for undergrads, and I'm unsure if this is a good idea. I'm afraid that I won't get a thorough, well-rounded education if I rush through things, but on the other hand it could be helpful get a head start and save tuition money. Could someone who has done this or knows about it give their opinion? Is this something to be looking for when comparing universities? BTW, I'm a high school senior, and I'm 99% sure that I'll be studying math in college.
