the paper setter was either drunk or was very harsh to young comers.......may be a brain-drain to tease the youth chemist as mush as possible......he had nothing in his mind but to crush many dreams of many people who had
waited long for PPSC to announce PCS after long time.
whatever it was, it was a disaster, total loss and paper was whimsical, capricious and flimsy for people who are MSC in main fields...........!
