i did a year of psych in GU before i changed universities to UQ.
it was good. i dont know why people dont like it.
you make friends really easily and people are generally helpful - there is heaps of help and the lecturers and tutors are very approachable... i guess thats why i did well there. when i was there... they used like really good textbooks.. especially if you do end up doing a human behavioural class.
anyways.. hope that helps... i still have notes and information on the classes.. even though that was like 2 years ago...
