I have just started preparing psychology, as I switched Indo-Pak, and I have found it really interesting but lengthy. So, if you want to opt it for score then will have to work hard.
Virtual University notes and lectures are good for understanding the subject and you can download the notes and watch lectures in their site http://www.vutube.edu.pk. These lectures and notes will provide you the Pakistani way of understanding which is necessary for our exams.
But be aware, these notes and lectures will provide you with an errand to understand basics, but you need to read books of Robert Feldman or Wayne Weiter (anyone) along with VU notes.
Besides VU notes I have comprehensive book of Psychology named "PSYCHOLOGY & ABNORMAL PSYCHOLOGY" containing approx 400 pages notes of an international author (name not given) in pdf format. If someone needs that book send me an email (see my profile) I will send it soon I open my email.
Stay blessed and remember in your precious prayers.
Regards.
