My little Sis did a Maths OU degree sometime back now whilst she was bringing up her family, wanted to keep her mind active etc. Whilst she left school with nothing, found she could apply herself to Maths rather well as it happens.. Long story short, each coursework handed in graded in the top .5% of the lot, went on to be part of Cambridge Uni and completed that plus PHD in Applied Math then continued to do a Doctorate in something or other.. Did her PGCE thingy and became a Headmistress and taught Math to “difficult” students in her own time and off Term time, went on to become quite involved in OU and Cambridge Uni Maths curriculum etc.
To say I’m proud of her is an understatement indeed.
Lecturers/coursework/support all excellent, though you do have to apply yourself to it, but if you need weekend refreshers courses they are there and a vast network of people doing the same course(s) to call upon if you have problems…
So, she did rather well out of it, if you have the time, why not???
