It is a nightmare: I am at university, and I have to pass a difficult exam. It is an oral examination, for which I have prepared, but probably not enough. I am nervous. The Professor’s office is in an old building, down a long corridor. Outside the room, a few students are waiting their turn. I go sit with them. I don’t know any of them. One of the girls greets me and says something. I don’t understand her. It sounds like what she is saying is “So, how many times have you tried this one?” I mumble something about this being my first time. (And hopefully my last! But I don’t even have the courage to say that. This, I feel, is no time for being over-confident.) I go through my notes, like everybody else does. After a few minutes, the door opens and out comes The Professor. I have never seen this man before.
I have been in my new job for four months now, and the learning curve has been steep … Wait a minute.
What has the learning curve been?
I never understood the expression “a steep learning curve”. When people say “a steep learning curve” what they mean is that something is difficult to learn and requires a large amount of effort (typically at the beginning). But presumably a learning curve plots the amount of whatever it is you have learnt on the y axis and time or effort or something similar on the x axis.
