In my humble opinion, Alone sher bano's psy books are not sufficient its better to add books like understanding psychology by robert s Feldman and introduction to psychology by Morgan..
SOME IMP THINGS TO REMEMBER REGARDING PSYCHOLOGY..
1)stick to syllabus.........mentioned by FPSC
2)Don't try to be innovative(apart from social psychology,industrial psychology & criminology)
3)use diagrams where necessary..e.g brain,neuron
4)don't try to crame things just make good concepts e.g theories in psy 1
5) go for urdu version of sher bano's books....it helps a lot in making basic concepts.
6)jahangir's 20 questions is also available,go for it too but (don't rely on it totally)i' am recommending this because such books become very handy in the absence of comprehensive book which covers the whole syllabus.



AS far as HEADINGS are concern in journalism and pak affairs..in my opinion...
Your paper is ur representative..when examiner is checking ur paper,u r not there to explain each and every thing ,so inorder to make it simple and easy for examiner use headings..


BEST OF LUCK
