I've forgotten almost everything from a lot of my old biology, chemistry, geography, and history classes but I feel like I've gotten so much more real world experience and can make so many connections that it would probably be much easier the next time around. Especially things that I felt like I was forced to memorize actually make sense once you draw connections to other places. I wonder why these things aren't taught like that. Or maybe it's just too difficult and too personalized for the current education system.
