There are a couple of universities that provide online instructions in various disciplines.
First and foremost is the Allama Iqbal Open University (AIOU) that has a huge line of online course offerings. (http://www.aiou.edu.pk/
). It is a pioneer of distance learning in Pakistan.
Secondly, there is the recently established Virtual University (http://www.vu.edu.pk/
) that also has several diploma and bachelor degree programs. It has a BA in psychology degree, too.
These are the first two universities that come to my mind. They are chartered and well-established. May be some newer ones have started in the past few years but I am not aware of them.
