<p>well US unis have general education requirements (classes you must take regardless of your major) and they normally include a number of humanites/science classes. You normally take them your first two years (before you start in on your major work). They’re all introductory classes, and it’s not like you’re studying 4 different courses. Americans want you to get a breadth of knowledge while at uni. UK unis want you to specialize and don’t have such GER’s.</p>
