Congratulations. I hope you get a career out of it. I used to love calculus as I treated it as puzzles. You're 36, returning to university. Good on you. What's wrong with your present occupation. What university are you attending? Just curious. I am 44, an artist. I wish I could go back to university and do more courses, but I am needed to run my ageing parents' shop. I am studying at home, though I'm not attending any colleges or taking tuitions, as I'm mainly self-taught. I am studying to make myriad self-improvements, some that would enhance my artistic career.
