Please advise what Diploma course can I enrol for that would Cover Maths and Physical Science if I did Maths Lit and No science, I need these two subjects for the field I want to go into.
The Maths and Science qualification you will need is a Level 4 course (National Senior Certificate). Generally you would need to pass Level 2, 3 and 4 before you could do either a Diploma (where any Maths or Science would be at Level 5) or a degree.
There are two options:
1. Do Maths and Science at a private institution (see the Maths & Science answer here http://www.careerplanet.co.za/faq/Training-related-questions)
2. Do a Diploma which does not require Maths or Science while tackling 1.
