okay, i've just checked the suject combinations for different streams, colleges.. realised that if i getting to cjc, my options of subject combination aren't as good as those of pjc, because i didn't do well for certain O levels subjects, and if i enter cjc i can only choose arts, not science, even though i did better for my science in Os. and i ain't interest in arts subjects like history or english literature. so now, i can only hope i getting pjc. yep.
