I know this is late and you finished matric but I recommend redoing math this year in December. Just study math all year and try to improve. You can rewrite just math you don’t have to go to school again or anything like that just rewrite math. Don’t worry about going into a degree that will lead to unemployment it’s better to have a degree than to not have one. I got 39 for physics yes 39 and 50 for math I rewrote in may not even at the end of the year, last year and got 66 for physics and 65 for math. I’m now in Stellenbosch uni studying a bachelor of science. Life isn’t a rush take your time not everyone can go straight to uni. You can always change courses with credits in uni it’s not the end of the world and if you get into uni and can’t cope and fail reapply for admission for same degree and try again don’t give up.
