I spent so long working on a problem for my course work, gave up decided to get what little marks I could. So tell me why when I run through the problem as I am leaving for uni the next day, I get the answer. I could lucky still change things but why did I have to lose sleep in vain :( I was half-sleep during my first lecture and of course it's the only lecture I don't have recordings for. I am pissed, I hate myself
