Going to the government sector is the dumbest thing you can do as any graduate unless you are a scholar. If you are not on the scholar tread, your performance does not matter as you can never exceed a certain rank and pay. It is for those without ambition or drive to work and just want a iron rice bowl to work till they grow old.
