Sir/Ma, before you make such allegations, have you realised that everything in this country is based on federal character, and quota system, and most of the time the northerners dont even fill their quota it is mostly filled by people from other parts of the country, why? because they are not even interested. Like the unity schools you are saying people from Zamfara hardly even go to school, so the few of them that show up with low marks are given admission so that the quota for zamfara state will be filled and even at that they dont fill it up, that is why sometimes you see an igbo or a yoruba with documents reading a state from the north so that that space that will not be filled by the northerners wont go to waste, meanwhile ppl from the south east and southwest fill up theirs because a vry large number of them go to school. It is so even with NDA. Do your findings and if i am wrong you are free to come and rebut wat i have said with a more superior argument. Thanks
