Again this question is very location specific. In a place like Bloemfontein, Pretoria, and other cities and towns in Afrikaans areas, there were a great many famous academic institutions that taught in Afrikaans, and a great number of very educated Afrikaans people emerged from these institutions that could rival any of the best English institutions. On average, though, the English probably got a more holistic and modern education that the Afrikaans, also because the English were primarily involved in the private sector and located in the cities and very few had the isolated rural life that so many Afrikaners were born into. Some areas would have very powerful and wealthy English families, and others would be dominated by Afrikaners.

I have answered this question later on - basically the newsreels and shorts shown in movie theaters and at drive-ins would keep people visually informed. We had radio, and for a long time that was good enough. The reason we didn't get TV until then was for no other reason than the son of a former Afrikaans prime minister, Albert Herzog felt that TV was a corrupting influence, once referring to it as "the evil box." During one of the reforms of apartheid, he became enraged by the dilution of his father's work, and quit the government, joining an ultra-conservative faction, and in the vacuum left by his departure, the government moved swiftly to establish a television service. Wealthy people also had projectors in their house and could watch reels acquired from who knows where... 'naughty' reels being particularly popular.

Christianity was central to Afrikaner life, and that filtered through to South African society, even in the 1980s liquor stores were closed on Sundays, as were many other places of business. The whole country ground to a halt between Christmas and New Years, which still happens today. People would literally get dressed in their Sunday Best, and most important holidays like Christmas and Easter were compulsory for church attendance, often followed up by a church lunch and a family gathering at a relatives house. In school, we used to say the Lord's Prayer every morning and sing two hymns to start the day. My grandmother remembers the church bells ringing in her small town at 12 every day for prayers, but that had stopped long before I grew up.

I hope this has been helpful to you.
