The best university for you will depend on certain individual criteria such as what specialisms you are interested in and what your preferred mode of study is. However, it may be useful to look at some of the US universities that are considered to offer the best online psychology courses. Based on variety of study on offer, price, end results and the number of students who expressed satisfaction with the course, the Walden University came top in a recent survey. Two thirds of students at this university said they would do the course again. The work was described as challenging, which normally should be seen as a good thing. However, in the Southern California University, which came second, almost 70 percent of students rated the course highly. It may be that this course is in second place because it was a bit more expensive than the Walden course.
