Nowadays, the globalisation of most developed countries is leading to a world which tends to have open frontiers, same currency and a flexible educational system. In particular, the U.S. universities seem to have some affinities with the British method of education. However, there are particulars that make the two very different and with lots of advantages/disadvantages when compared to the other.The main difference between the two educational systems is that in U.S. universities there is a freedom of choice of workload (i.e. credits to be taken per semester) compared to the heavy and long classes that a student must take over a whole academic year in U.K. institutions. For example, being an American academic year divided into two semesters (plus two short summer sessions) that last each four months, it is possible to choose more or less classes depending on the student necessities.
