(Weil du ja das Referat in English halten musst, hier gleich einmal eine Übung)
Although I lived for quiet a long time in South Africa unfortunately it's too long ago to give you an up to date answer. When my own children started school in Jo'burg in 1972 they went to a 'all Whites' school because this was the rule in those days. Black children went to schools in their townships, white kids went to schools in their suburbs. To compare these systems is actually not possible because white kids made Matric which was a university entrance diploma comparable to our German Abitur. This was basically also possible in a 'Black school'.(remember the education of Nelson Mandela, he even became a Attorney of Law back in the early 1960's). But this was not possible for the 'normal' black kid which perhaps lived in a rural area far away from any form of schooling. And if there was a school close by the general time they spend in school was perhaps 4-6 years. But also remember the former South African President Zuma. He only went to school for only 4 years, spent most of his time as a young boy to take care of his family's (or tribe) goats (so they say). And yet he became the most corrupt politician of the Republic of South Africa ever since.
Today I spend 6-8 weeks every year in SA and know only little but I read the papers online and have the impression that the chances for a Black boy or girl are amazingly good IF they are willing to learn and their parents give them enough support. But what I read from the universities students spend more time demonstrating against all and everything (but true enough also against higher fees), but unfortunately also against a lot of rubbish their self appointed leaders. For instance 2 or 3 years back students demonstrated for the destroying of historical monuments. One can discuss a lot about a man like Cecil Rhodes, and maybe students are made for this matter - alright, but their main target should be their education and qualification and not torching buses and metro trains.
I hope this gives you a bit of an impression what at least was it like to go to school in those days.
By the way, school uniforms a an old tradition in South Africa and are still in use
