i agree with maha
one of statement of usmani sb told to me by one of my friend:
"for most of the candidates 80-90% of css ends on day1 of exams,this is because their other subjects are well prepared except english.another 10% depends on islamiat paper."
if we see dms of most candidates who failed to qualify we find that they failed in these 2 subjects.
moreover,candidates think that english, Pakistan affairs and current affairs are not going to give much marks. so they concentrate more on optional.
everyday science paper is a problem for many candidates who do not have a science background so they have to suffer in exams.
you will see inquiry of beginners asking ' which subjects are more scoring?'
this shows that scoring matters more. no doubt scoring matters but passing all subjects is necessary and all subjects demand time.
so what one should do :
give all subjects proper time
make notes keeping in view syllabus,past papers and trends
practice past papers
make outlines of their notes
do writing practice daily and if possible get it checked
only one knows his weakness and must work on it
