DD is leaving home soon & I will have 'free-time' - I know not what this is 
I did my OU degree while juggling a home, a FT job & a time intensive DD and I can't afford to sy=tudy any more OU formally
Am I right that there used to be a open bit you could just go & study? That was free?
If so could I go back and study some Maths stuff (not really sure what) I'd probably need some remedial stuff as apart from the odd simultaneous equation or spreadsheet I have done no maths for decades
Any ideas where I should start?
