I like math. It's the only subject that you can't go wrong with (and if you suspect any wrongdoing then know that there is always a way of checking).
My teachers in high school always told me that professors in colleges and universities will expect you to be fully responsible of whatever happens (even if what happens is totally out of your control). As a student one is expected to find out about things in advance and remain on the ball. Sad to say, I suffered a dozen or so blunders in my early days.
