I got an A for my maths IGCSE and I don't know my tables either. 
So what does she think she is going to do with those subjects then?
I don't think she has the first idea. Lets get the qualifications first.
My suggestion is that she gets a degree (prolly geology) and then takes off to pastures abroad. So far that is the only suggestion she will admit to taking on board ~ although it was me who found the college, made the appointment, got the application forms, arranged the initial interview and will be paying the costs not covered by grants etc.
BUT what do I know? ~ I'm just a boring old fart, past his time, who interferes in her life.
