hello dear, i advice you not to opt physics as most of the time one end up with nothing but regretting in retrospective analysis that one do in the month of oct/ nov jab amaal nama FPSC phone kar k poocha jata hai. go through the physics result in year 2011/ 2012. i think the result of these years would be "suffice" to divert your mind from the troubled journey that leads to suicidal destination(reasoning done in good faith)
