Don't understand anything at my accounting job

So I started working for this company just about a month now and I literally do not know what I'm doing and all the college experience I've had so far about accounting rules seems generally useless. I'm just asked to do a bunch of tasks which someone helps me with but its something a kid could do. The part where I'm sort of anxious about is that I feel like I'm taking too long to do these tasks and I also don't understand what I'm doing... at all. If I was asked to explain why I'm doing this thing I wouldn't know at all, I just do what I'm told and hoping that I'm not messing up. My slow pace has me thinking I might get fired as well. Is this normal or am I screwed?
