well i must say that u should have deep study of the optional subjects those which seem to be interesting to u,
well i tell u about my experience that i took three months to decide about my optionals,
i have changed 3 times my decision of optionals,
i had to appear in 2010 but i was not sure about the optionals that's why i dropped my this attempt and i have finalized those subjects which are scoring from fpsc point of view and those which students do not opt ....
