I already did calculus and linear algebra, before and during my first semester at University back in 2011-2012. I didn't attend any lecture or put much effort into it, and I got bad grades (although I passed). I don't remember anything about them, and I might have to do them again (I'm not sure if they're transferable). I have enough savings to pay for university in my home province without taking any loan.
