a.o.a friends i have started preparing for p.c.s exams 2010.....i dn't know when they will be but its better to start now ....becoz my c..s.s experience showed me that every day every hour every minute is priceless and important and as early as u start preparing the better u can prepare and its easy to revise in close days of exams.....i m taking the same optional subjects , that i took in c.s.s. 2010 .....changing of optional subject wont help much.
