They're not coping academically because the majority of them are poor, not because they're black. It's an observable trend the world over that poor children are more likely to fail academically than their more priviledged counterparts, even in ethnically homogeneous countries like Japan and eastern European countries. Therefore your statement that black people cannot cope academically is false. That's why I stated that I went to a private school, not to brag, but to indicate that I had a much easier time acquiring an education than most black students. If your day to day life includes worrying where your next meal is going to come from, planning your 10km route home that will minimise your chances of being robbed/getting caught between a gang shootout because the area you live in is so dangerous etc. academics are the last thing on your mind.
Poorer schools also tend to be more dysfunctional than wealthier ones and on average have inferior teachers. If your teachers didn't show up everyday, or if they did, they showed up 3 hours late and drunk, it would almost certainly have a negative impact on your marks. The schools will have a shortage of desks, textbooks, broken doors and windows so it's extremely cold in winter. They will have some students who stab others as they have already have been recruited by criminal gangs in the area. All of these problems build up, disrupt classes and impede a students academic progress.
Succeeding in university is a different matter entirely. Some of the lucky ones who do make it to university have never even used a PC in their lives which already puts them at a disadvantage in uni, especially in the scientific/engineering courses and maths. It has also been observed that children with parents that have graduated from a university are more likely to succeed in varsity. Your statement that blacks cannot compete academically is false and should be more along the lines of the poorer you are the more likely you are to fail academically. These students are failing because they're poor, and the majority of the poor just happen to be black. There not failing because they're black.
