Sociology and journalism are easy subjects even I studied sociology for 2 months only and get 65 marks in my first and last attempt.
well css subjects are 12. you need to divide your time carefully because you have just one month roughly in your hand.
For optionals give half an hour to 40 min daily per subject.
For compulsory give an hour for pak affairs and islamiat
An hour for EDS and current affairs + read a news paper daily.
And an hour for precis and composition.
For essay write 2 essay from past papers twice a week.

Check in which subjects you are strong......... give them less time and spare more for your weaker subjects.
All the best.
