from this chapter in previous 13 years these type of questions were asked:
tools for clinical diagnosis

DSM IV now DSM 5

psychosomatic vs somato form disorders.

regarding priorities
paper 11 is like this

1.MCQs
2.development
3.development
4. disorders
5.therapies
6. intelligence and mental retardition
7. juvinile delinquency, drug addiction, sexual offences, industrial psychology
8. short answers any 4

now depending upon diagrams , flowcharts, keys, tables, sketches, applications , thoughts, creativity
you should go for
1. mcqs
2. disorders
3.therapies
4. intelligence
5. short answers ( 5 questions completed)

if there is any problem ,
one should go for juvinile delinquency, drugaddiction , ( in past 13 years 13 times question of juvenile delinquency was asked, under same heading,k biological and sociological factors)

it doesnt mean you shouldnt go for development . cover it out but first go for priorities. try to leave research question because applied form is mostly asked that is difficult to elaborate , . secondly research also confines one .
